I. SUMMARY
The problems of supersonic combustion in a diverging duct were examined
analytically_ and the results of this study were compared with test results
from the HRE two-dimensional combustor rig. The effects of temperature_ pres-
sure 3 duct divergence, amount of vitiation and initial concentration of
radicals on the chemical kinetics of the hydrogen-air system were investigated.
It was found that supersonic combustion of hydrogen-air in a diverging duct at
low mixed temperatures (around 2000°R) is very sensitive to chemical kinetics
effects. The ignition delay time decreased with increasing pressure but this
effect was reversed in the pressure range of I to 15 atm depending on the
initial temperature. The ignition process was enchanced by the presence of
free radicals_ but the relative effects diminished rapidly as the initial con-centration was increased.
A detailed chemical-kinetic simulation of the HRE two-dimensional com-
bustor test results indicated that low chemical efficiencies in the second
stage were not caused by chemical-kinetics but were due to.inadequate mixing.
This conclusion was further strengthed by tests reported by General Electric
(Reference I-I) in which low chemical efficiencies were observed when fuel was
injected into a constant-area duct followed by a divergence section_ with an
inlet static temperature as high as 2500°R.
It is postulated that intimate mixing requires turbulence with small but
high energy level eddies. The various injector geometries used in the two-
dimensional combustor tests probably did not cause sufficient turbulence in
the mainstream, evidenced by lack of sufficient flow separation. The low level
of turbulence could be due to the favorable pressure gradient in the diverging
duct and to the relatively high temperatures upstream of the second stage
injectors. Further exploration in this area is urgently needed.
The analytical simulation of the AIM engine indicated that the chemical-
kinetics effects will not adversely affect the second-stage combustion process
in the flight Mach number range of 5 to 8.
The results from the two-dimensional combustor tests lead to the prediction
of low second-stage combustor efficiencies in the AIM engine unless methods
for enhancing the mixing process can be devised. Turbulence could be generated
by a metallic coating on the combustor walls. This coating can be applied with
varying degrees of surface roughness to produce different levels of turbulence,
Currently_ five additional igniter stations are being installed in the
AIM combustor. The igniter jets are directed upstream to produce additional
sources of turbulence as well as ignition energy.

2. INTRODUCTION
(
The problems of supersonic combustion in a diverging duct were evident
in the HRE two-dimensional combustor component test program. In these tests
low chemical efficiencies_ in the order of 50 to 60 percent, were encountered
regardless of injector geometry_ equivalence ratios, and inlet total tempera-
ture. Various injector geometries and equivalence ratios aimed at improving
the mixing, and high inlet total temperatures (5800°R) which should enhance
the chemical reactions were tried. However, all attempts failed to improve
the combustor performance. A subsequent survey of the literature indicated
that low chemical efficiencies were also obtained by a number of investigators
(Reference I-I I-2, and 2-I) whenever a diverging duct was used. Cookson
(Reference 2-II found that a hydrogen diffusion flame could not be maintained
in a simple conical combustor of 0..75 deg divergence and 50 in. long. Com-
bustion was observed to occur after the Mach disc which was formed at the
combustor exit. Cooksonts experiments strongly suggest that chemical kinetics
have a significant affect on the problem. Therefore 3 an investigation was
initiated to study the various effects of chemical kinetics using existing
computer programs in order to obtain a better understanding of the problem.
The investigation was divided into four phases. First_ a parametric
study was conducted to obtain the basic understanding of the chemical kinetics
from the effects of various independent variables such as temperature, pres-
sure, divergence_ degree of vitiation_ and initial concentration of radicals;
second, the mechanism of ignition delay was examined in a simplified analytical
form in order to obtain the essential correlation parameters which otherwise
could not be obtained from computer programs; and third_ a comparison was made
between the computer program results and Cookson's experiments in order to
substantiate the validity of the kinetics programs. Fully-mixed and partially-mixed models were simulated in a shear-layer combustion program (Reference 2-2)
to try and analyze and compare with the results from the two-dimensional com-
bustor test program. Finally 3 a chemical kinetic analysis of the AIM engine
was performed. A brief examination of chemical kinetics using a two-dimensional
kinetics program was also made.

3. PARAMETRIC STUDIES
An investigation of the chemical kinetics of a premixed hydrogen-airsystem was conducted. The investigation was directed toward clarifying theeffects of static temperature_ static pressure_ flow velocity, equivalenceratio_ vitiation 3 initial radical concentrationj and combustor divergence onthe chemical kinetics. These effects were determined through use of a one-dimensional chemical kinetics computer program (Reference 5-1).
3.1 THE DETAILED HYDROGEN-AIR CHEMICAL KINETIC MODEL
The reaction mechanism of the hydrogen-air reaction assumed to be com-prised of the II reactions is shown in Table 3.1-1.

The symbol M represents a "third body" 3 i.e• 3 any chemical species. The
third body acts as an energy source or sink in chemical reactions. Steps 23
33 and 7 are branching reactions since two chain carriers appear in the
products while only one enters into the reaction• Steps 5 and I0 serve to
break the hydrogen-oxygen chain by removing (H) and (OH) from the mixture.
Thus 3 chain-branching reactions are responsible for the production of pro-
gressively larger concentrations of chain carriers. Unless the chain-branching reactions are balanced by chain-breaking reactionsj the reaction
rate will increase until it becomes sufficiently rapid to be classified as
an explosion.
The reaction rate constants are expressed in the standard Arrhenius form
given by
FKf = DT E exp. T
Kf
Kb =K_Q
KEQ = OCTEC exp. (FC/T)
where D 3 E_ Fj DCj EC and FC are the constants and are presented in Table 3.1-2•
The constant 3 D 3 for reaction (5) was multiplied by the weighted third body
efficiency factor 3 bW
3.2 RESULTS AND DISCUSSION
5.2.1 Effect of Static Temperature
Chemical kinetic calculations were made as a function of initial static
temperature for clean air as defined in Table3.2-1. In all of these calcula-
tions 3 the initial static pressure (P = I atm)3 equivalence ratio (¢ = 0.5)3
initial flow velocity (V = 4500 ft/sec) and combustor flow area were held
constant.
The results of these studies are presented in Figures 3.2-1 through 3.2-7.
In Figure 3.2-13 there appears a significant time delay before any appreciable
temperature rise is observed. This period is referred to as the ignition
delay period. During this period 3 little change occurs in hydrogen molecular
species but large changes in H20 _ O_ H3 and OH concentrations occur as shown
in Figures 5.2-43 3.2-53 and 3.2-6. The two body reactions are relativelyfast and lead to an overproduction of radicals. At the end of ignition delay
period 3 the third body reactions begin to play a dominant role leading to
recombination and depletion of radicals with the accompanying energy release,
The time for the process to proceed from the end of ignition delay to an
equilibrium state is referred to as the reaction time. Due to an inherent
difficulty of the computer program in reaching the equilibrium state_ the com-
putations were limited to 3 min of computer time; thereforej the final
equilibrium state was not reached in most cases.

There are a number of quantitative definitions of the ignition delaytime which can be found in the literature:
(a) The time required for the concentration of OH radical to reach
10 -6 mole/liter (Reference 3-2)
(b) The time at which a point of inflection of atomic hydrogen isobserved (Reference 3-3)
(c) The location of the intersection of the slopes of the initial andmaximum temperature rise (Reference 5-4)
(d) The time at which a point of inflection of OH radicals is observed

/
(e) The point of 0. I percent density decrease
(f) The time it takes for the temperature to increase 5 percent
of the total temperature rise (Reference 3-5)
All these assumptions in defining the ignition delay period are reason-
able and lead to the same conclusion (Reference 3-6). For convenlence 3
definition (a) is used in this report. The summarized results are shown in
Figure 3.2-7. As expected, the ignition delay increases with decreasing
temperature and does not ignite at all when temperature decreases to 1800°R.
The resultant pressure and chemical efficiency variations are presented in
Figures 3.2-2 and 3.2-3. The chemical efficiency is an approximation base_
on the percentage of reacted hydrogen molecules by weight. For complete
combustion, the percentage of unreacted hydrogen molecules increases with
combustion temperature. Thereforej the approximation of chemical efficiency
will be pessimistic, especially at high combustion temperatures. The approxi-
mation was used as a calculation convenience and is permissible because only
qualitative results are being sought.

3.2.2 Effect of Pressure
Chemical kinetics calculations were made for a hydrogen-air mixture at
a temperature of 1900°R for several initial pressures in a constant area duct.
The ignition delay times obtained from these calculations are presented in
Figure 3.2-8. At low pressuresj the collision rate of molecules is small due
to the low density of the mixture, thereforej the chain-branching reactions
are slow which results in long ignition delays. As the pressure is increasedj
more and more molecules collide per second and chain-branching reactions
become faster and faster resulting in shorter ignition delays. However 3 when
the pressure is further increased_ the ignition delay time reaches a minimum
point beyond which it increases with increasing pressure. This phenomenon is
caused by the following chain-breaking reaction:
H + 02 + M = HO 2 + M
where M represents any kind of molecules? such as H27 027 H203 N2, etc.
Ordinarily HO2 is a very unstable combination of hydrogen and oxygen because
more energy is released upon its formation than is required to bring about its
decomposition. However_ if another molecule is present to absorb the excess
energy released from the formation of H023 the latter may exit as an inter-
mediate product in the chain reaction. The "third body"_ M_ acts as an energy
acceptor and stabilizer to this reaction. This reaction serves to break the
hydrogen-oxygen chain reaction by removing the free hydrogen atom from the
mixture. As the pressure increasesj the concentration of "third body"increases and the effect of chain-breaking becomes greater than the effect of
chain-branching; thereforej it increases the ignition delay time.
Figures 3.2-9_ 3.2-10_ and 3.2-11 show the temperature_ pressurej and
chemical efficiency distribution along a constant area combustor with various
inlet static pressures. The concentration of species is given in Figure 3.2-12
at an inlet pressure of 25 psia.
The effect of pressure on ignition delay for an initial temperature of:
2200°R is presented in Figure 3.2-13. The ignition delay time decreases with
increasing pressure and no minimum point was observed up to a pressure of 65
psia. The reaction is slowed down slightly in the range of pressures from
65 to I00 psia. Figures 3.2-14_ 3.2-15_ and 3.2-16 show the temperaturej
pressure and chemical efficiency distributions_ respectively3 along the duct
with initial inlet temperatures of 2200°R.
Calculations were also made for other inlet temperatures which are shown
in Figure 3.2-17. As the static temperature is increased from 1900°K to
2200°R3 the pressure at which the minimum delay time occurs moves progressivelyto higher values and the curves become flatter. Thus_ at the higher initial
temperature of 2200°R3 ignition delay was not affected as much by staticpressure as at an initial temperature o_ 1900°R.

significant. Therefore 3 at low initial static temperatures 3 vitiation caused
higher ignition delays. At initial static temperatures above 2200°R the
difference in ignition delay time for vitiated and clean air were less than
20 _sec and therefore can be considered negligible.
3.2.5 Effect of Initial Radicals (Carriers)
In order to see the effect of initial radicals or carriers on the
chemical reaction as a function of initial static temperaturej chemical
kinetic studies were made for two vitiated mixtures with initially non-
equilibrium free-radical concentrations (see Table 3.2-2). Results are
shown in Figures 3.2-23 through 3.2-28 as plots of temperature 3 chemicalefficiency 3 and pressure versus combustor length with different initial
temperatures for I0 percent and 2 percent of initial carriers. The percentof carriers indicates the amount of hydrogen consumed in a constant area
duct if the initial temperatures were 2200°R. As expected 3 the presence of
initial carriers accelerated the chemical reaction by the chain-branching
reactions of Table 3.1-13 steps 23 33 and 7. Initial carriers had the effect
of transposing the region of long ignition delay to lower temperatures. Theautoignition temperatures (those temperatures below which chemical reactionceased to occur) were lowered to 1600°R and 1400OR for the vitiated mixtures
of 2-percent and IO-percent reacted-chain carriers respectively 3 as comparedto 1800°R for clean air. Ignition delay could not be determined by the
previously used criterion of OH concentration because of the presence of
initial carriers. Results based on the chemical efficiencies of 80 percentand 40 percent for both vitiated mixtures and clean air are shown in
Figure 3.2-29. For a given combustor iength_ Figure 3.2-29 gives the
required initial static temperature to produce a given chemical efficiency.

3.2.6 Effect of the Divergence
The effect of divergence was calculated for clean air as a function of
initial static temperature. The results for an initial temperature of 2500°R
are presented in Figures 3.2-30_ 3.2-312 and 3.2-32 for different values of
I dA (change of area ratio per unit length)Ai dx
Examination of Figure 5.2-50 indicated that ignition delay increased with
(idA /with increasing divergence Ai dx and that the reaction proceeded very slowly
at values of divergence greater than approximately I/I0 cm "I. The increased
ignition delay with divergence was due to the relative production rates in the
chain-branching and chain-breaking reactions. At low values of divergence_
the production rates in the chain-branching reactions were sufficient to offset
the production rates in the chain-breaking reactions. At large values of
divergence 3 the decreasing values of pressure and temperature effectively
quenched the chain-branching reactions and the production of chain carriers was
not sufficient to initiate the highly exothermic recombination reactions. For
example 3 to achieve a chemical efficiency of 80 percent within a combustor
length of _, cm_ the required initial static temperature would be 1670°R3
1910°R and 2/_lO°R for lO-percent_ 2-percent and O-percent carriers_ respectively.

Calculations were also made for clean air at an initial static temperature
of 2200°R. The results presented in Figures 3.2-33_ 3.2-34_ and 3.2-35
indicated a trend similar to the higher inltial static temperature case with
the reaction essentially quenched for values of divergences greater than about
6/I00 cm-I.
Examination of Figure 3.2-33 indicated that ignition would occur in a
diverging duct when concentration of OH had reached 10 -6 moles/liter before
the temperature had decreased below about 1950°R.
I dAIn Figure 3.2-36_ the ignition delays plotted versus AT _ for initial
static temperatures of 2200°Rj 2350°R3 and 2500°R indicated that the effect ofdivergence on ignition delay decreased with increasing initial static tempera-ture. The effect of increasing divergence was to increase the length requiredfor combustion. This increased length was due to (I) the temperature andpressure effects on ignition delay_ and (2) increased flow velocity.

4. CHEMICAL KINETICS DURING THE IGNITION DELAY PERIOD
Although more than a dozen chemical reactions are involved in a hydrogen-
air combustion process 3 not all reactions are significant at all times. In
the isothermal induction period the major change is in the buildup of the
atomic species (H) and (0) and the (OH) radicals. The significant reactions
are either mildly exothermic or endothermicj and the system is essentially at
a constant temperature. The production rates in reactions which involve large
activation energies are insignificant during this isothermal induction period.
The length of this period is affected both by the initial temperature and by
the pressure. For the HRE application_ the ignition delay must be considerablyless than one millisecond. Significant production rates occur in the following
reactions during the induction period=
i0 I0 15..__1.1 (Ref 3-4) (4-1)H + 02--_OH + 0 k I = 5.64 x e - RT

Where the reactance concentration is in units of mole/lite_ R is in kilo-cal/

remained relatively constant for a given initial condition. Also during the
ignition delay period 3 the molecular concentrations did not change materially 3
and the ratio ofll___2defined" as 2_ could be considered constant. Therefore 3 in

Also shown in Figure 4.1-1 were the shock tube experimental results taken
from Ref 4-1. The definition of ignition delay used in Ref 4-1 was based on
the sharp rise in temperature observed by the infra red optical system. If
this sharp temperature rise occurs near an [OH] concentration of 10-6 moles/

The disagreement between these two methods may be attributed to theignorance of the third body effects of water vapor in the simplified solution.
The ignition delay is also affected by the initial [OH] concentration.The influence of this factor can be deduced from equation (4-18) as follows:
'r = (log I0 "6 - !o9 [OH]i)
Increasing the initial [OH] concentration will reduce the i_nition time.A typical initial [OH] concentration is I0-10 mole/liter at IO00UK.

The increasing ignition delay in the second explosion limit is clearly
illustrated by Figure 4,1-1. For an initial temperature of IO00°K or iessjthe ignition delay time increases with pressure. This phenomena has been
known for some time and is due to the formation of the [H02] radial by
reaction 2 which is (H + 02 + H - HO2 + H). This reaction removes the atomic
hydrogen without the benefit of producing a new active species. Since it is a
three-body-collision process_ its rate is proportional to the second power of
the pressure as compared with the two-body-collision process which is propor-tional to the first power of the pressure. The ignition delay time will
increase with increasing pressure when the rate of reaction 2 increases fasterthan reaction 3.
The initial rate of [OH] production is primarily given by the molecularcollision denoted by the reaction
H 2 + 02---_20H
At time zero 3 it is assumed that the production rate of [OH] in the above
reaction balance the [OH] consumption rate of reaction 4.

5. TWO-DIMENSIONAL EFFECTS IN A DIVERGING COMBUSTOR
A few exploratory calculations were made in order to investigate two-
dimensional effects in supersonic combustion of a premixed gas in a divergin 9
combustor. Since this effort was very limited in scope_ only a brief qualita-tive discussion will be given here.
Numerical solutions were obtained using the method of characteristics with
finite chemical kinetics in an axisymmetric combustor. The computer programdescribed in Reference 5-1 and 5-2 was used to obtain these solutions.
The hot portion of a boundary layer can give beneficial effects in theinitiation of combustion (assuming that there is fuel in the boundary layer).
Ignition and combustion in the boundary layer can produce an expansion of the
boundary stream tube. Compression waves are induced in the main flow where
the stream tube begins to expand. Farther downstream_ when combustion is
nearly complete in the boundary layer_ expansion waves appear in the main flow,
This situation is depicted schematically in Figure 5,0-1. At the duct center-
line the pressure waves appear downstream of the start of the compression
surfaces. For typical AIM Mach numbers this distance is of the order of the
duct height.
Compression heating of the mainstream 3 caused by combustion in the boundarylayer stream tube_ was predicted in Reference 5-5 using a quasi-two-dimensional
model which assumed a uniform pressure across the combustor_s height. The
"overshoot" (See Figure 5,0-1) predicted by the truly two-dimensional solution
has an effect on combustion which is usually benefica] and which is not pre-
dicted by the quasi-two-dimensional approach,
Howeverj the beneficial effect of a high initial temperature in the
boundary layer can be offset. When a diverging portion of the combustor is
reachedj the boundary layer stream tube is the first to be turned (expanded).
This can result in quenching of combustion in the boundary layer.
Alsoj choking can occur in a single stream tube 3 possibly leading to a
disturbance which propagates upstream in the combustor and causes an adjust-ment in the air flow. Such a disturbance cannot be predicted using the
existing steady-state model. However 3 this phenomenon could conceivably occur
in a real combustor and be a factor in boundary-layer separation.

3.2.3 Effect of Equivalence Ratio
Chemical kinetics were calculated as a function of equivalence ratio with
clean air. Results presented in Figures 3.2-18 through 3.2-21 indicated that
ignition delays are essentially constant for the range of equivalence ratios
investigated.
3.2.4 Vitiation Effects
Precombustion of hydrogen with oxygen replenishment as a means of perheated
air is denoted by the term "vitiated air." The effect of this vitiated air on
the ignition delay time of the H2 -air reaction was investigated.
Clean air at several initial total temperatures was precombusted at a
pressure of 20 atm with varying amounts of hydrogen at room temperature. The
combustion products were then expanded to a pressure of I atm in order to
obtain their equilibrium compositions. Note that in the precombustion 3 oxygen
was added to preserve the same 02 mole fraction as in clean air. The percent
of vitiation or percent of fuel by weight (fuel considered as H 2 and 02 with
the weightlOf). 02 12.2 times that of H2) was varied from 0 to 50 percent (seeTable 3-2-
Chemical kinetic calculations were then made starting with the vitiated
equilibrium species concentrations at I arm pressure. Hydrogen at an equiv-alence ratio of 0.5 was allowed to react at constant area with the vitiated
air. The initial conditions consisted of a static pressure of I arm and a
velocity of 4500 ft/sec at several initial static temperatures from 1850°R to
2300°R. The results of these calculations are presented in Figure 3.2-22.
Ignition delays were determined from the time required for the OH concentra-tion to reach 10 -6 moles/liter. The dotted lines are the estimated values.
Examination of Figure 3.2-22 indicated that the degree of vitiation had
a strong effect on ignition delay time at 1850°R and 2000°Rj but a negligibleeffect at 2300°R. Even small amounts of vitiation at 1850°R caused the
ignition delay time to increase very rapidly and for all practical purposescaused chemical reactions to cease. Chemical reactions also ceased at 2000°R
initial temperature near 25 percent vitiation.
As the amount of vitiation increased_ so did the amount of water vaporand OH. The initial concentrations were shown in Table 3.2-1. The water
vapor acts as a very efficient third body (third bodies act as energy sourcesor sinks in chemical reactions) as shown in the reaction:
H + 02 + M = HO 2 + M
This reaction removed H from the mixture causing a quenching of the
chain-branching reaction. At low temperaturej the chain-breaking reaction
H + 02 + M = HO2 + M predominated. At the higher temperaturesj the thermal
dissociation of H20 and chain-branching HO2 + H2 = H202 + H then became

6. COMPARISON WITH TEST DATA
Considerable attention has been given to the theoretical chemical kinetics
of premixed hydrogen-air supersonic combustors. However, little of this work
has been done for diverging combustors of specified geometry. In this type
of combustorj conditions can occur in which the expansion waves cause the
temperature and pressure to decrease from their entrance values with combustor
length. By contrast 3 if constant pressurej constant area, or constant Mach
number is assumed 3 the temperature never decreases appreciably (unless largewall heat losses are considered).
Because the rates of the elementary chemical reactions in the hydrogen-
air combustion system are strongly dependent on concentrations and temperaturej
it seems plausible that under some conditions divergence of a supersonic com-
bustor could lead to significant adverse effects on the chemical kinetics even
though the initial temperature is above the autoignition temperature.
Experimental results reported by Cookson 3 Flanagan 3 and Penney (Reference
2-1) provide an example of conditions under which a small change in divergence
angle had a dramatic effect on combustion.
Cookson et al. report that for a combustor inlet air total temperature of
approximately 1900°K and at Mach 1.98_ a flame was initiated in a combustor
which consisted of a 5-in.-1ong constant-area section followed by a 25-in.-
long conical section diverging at a l-deg angle; howeverj with the same inlet
conditions no combustion took place within a completely divergent ductj even
with a divergence angle as small as 0.75 deg.
Axial injection was used in Cookson's experiments. This eliminates com-
plicating effects associated with cross-stream injection and makes the experi-
ments more amenable to one-dimensional analysis.
In an attempt to explain Cookson's results_ chemical kinetic calculations
were made using two different computer programsj each using a different set of
chemical kinetic rate constants. The first program used (Zupniks) is described
in Reference 5-I.; the second (Frey's) in Reference 2-2. The chemical reactions
and rate constants used in the two programs are listed in Tables 6.0-I and
5. I-2. For initial calculations the higher frequency factor listed in Table
3.1-2 was used for reaction 5.
Because the analytical models used were one-dimensionalj there was some
question as to what initial conditions were appropriate. In the Cookson
experimental work the fuel and air started out unmixed at the combustor
entrance. For the chemical kinetic calculations_ premixing was assumed. A11
initial parameters were kept constant except the initial temperature 3 the

combustor 9eometryj and the equivalence ratio. Cookson reports an air total
temperature of approximately IBTO°K (5366°R) and an air Mach number of 1.9B at
the combustor inlet. The air and fuel static temperature apparently were about
1176°K (2117°R) and 290°K (523°R) respectively. Preliminary calculations were
made using ¢ = 0.50. This is slightly above the highest value (¢ = 0.45)
given by Cookson.
5.1 RESULTS
At an initial mixed fuel-alr temperature of 1150°Kj the calculations
indicated a chemical efficiency of over 60 percent in the 0.75 degree all-diverging combustor. At an initial temperature of i130°K the chemical effi-
ciency calculated was less than I percent for the same geometry.
For the 30-in. duct with a 5-in. constant-area section and al-deg diver-
gence angle 3 the calculated chemical efficiency was 60 percent or greater fortemperatures of 1115°K and above. This indicated that the calculations with
initial temperatures in the band of approximately 1115°-1155°K (2007°-2054°R)
agreed qualitatively with Cookson_s results in one respect; combustion
occurred in the duct having a 5-in. constant-area section, and did not occur
in the all-diverging combustor.
To avoid choking in the theoretical model at an equivalence ratio of 0.5_
the initial temperature had to be more carefully selected. Raising the
initial temperature just a few degrees above 1115°K could lead to choking in
the divergent portion following the constant-area section.
A few calculations were made for an equivalence ratio of 0.33 using both
Zupnik's and Frey's programs_ with an initial temperature of 1115°K and thetwo different sets of rate constants listed in Table 5. I-Z and 6.0-1. The
initial conditions are listed in Table 6.1-1. Both programs again predicted
the result found by Cookson--that combustion would occur in the combustor
with a constant-area section followed by a I-deg divergence 3 but not in the
combustor having a constant divergence angle of 0.75 deg. Furthermorej when
a constant-area combustor was specified 3 the calculation indicated choking.
This apparently is in agreement with Cookson's observation that a shock wouldform in the constant-area combustor.
The computed axial temperature profiles for the two diverging combustor
cases are shown in Figures 5,1-1 and 6,1-2. In the case with no combustion
(Figure 5.1-2) the temperature profiles from the two programs were very
nearly identical and only one curve is shown.
Disagreement between the results from the two computer programs is due tothe differences in rate constants which were used rather than the differences
in mathematical method. The curves are labeled with the program name only forconvenience.
One of the conspicuous features of the case with no combustion is the
decrease in (OH) concentration which occurs in the results from both programs
and begins well along the combustor length_ as shown in Figure 5,1-3. (Adecrease in (0) concentration begins farther downstream; see Figure 5,1-4.)

Reaction rates from the Frey program indicate that the reversal .in the time-derivative of (OH) concentration occurs when the rate of the OH-destroyingreaction
OH + H2 - H20 + H (6-I)
outweighs the combined rates of the two dominant OH-producing reactions
02 + H - OH + 0 (6-2)
H2 + O - OH + H (6-3)
UNCLASSIFIED 70-6319_ A_,_c,_=_ Page 6-8
UNCLASSIFIED
/ .
The (OH) reversal is apparently only a symptom and not the basic cause of the
quenching of combustion in the analytical study. Exploratory calculationsshowed that when the rate of Reaction (6-1) above was suppressed by lowering
its rate constant, the destruction of (OH) was accomplished by the reaction
OH + OH - H20 ÷ 0 (6-4)
Similarly, when in a further calculation Reactions (6-I) and (6-4) above were
both suppressed 3 two more reactions took their place to cause net destruction
of (OH).
It is believed that the quenching observed in the computer programs is
due to a decrease in the rates of all the reactions_ which is caused simply by
the lowering of static pressure and temperature associated with expansion of
the gas. The OH reversal seems to be a part of the adjustment of the chemical
process to the slower rates. Changing the rate constants of the OH-destroying
reactions changes the overall process ratej but apparently does not change themechanism.
The pressure profile reported by Cookson for _ = 0.35 and those computed
by the two chemical kinetic programs for the geometry in which combustion
occurred are shown in Figure 6.1-5. Computed profile forms in disagreement
with the experimental profile is not surprising; the heat release was spread
out due to finite-rate mixing in the experiments_ but in the theoretical pre-mixed model the heat release occurred over a short axial distance. Agreement
in the constant-area section would probably be improved by considering the
effects of mixing and of wall friction.
As previously mentioned_ a high frequency factor was assigned to the rate
constant for reaction 5 in using the Zupnik program. This frequency factor
was about 2.5 times greater than that in the original reference (see Table
5.1-2). Decreasing the frequency factor of this reaction has the effect of
increasing the overall heat release rate. When the lower frequency factor in
Table 3.1-2 was used 3 the heat release was accelerated enough to cause choking
in the combustor having a constant-area section although the calculation for
the conical combustor still indicated no heat release. Thus for a marginal
case the results can be very sensitive to the rate of the H + 02 + M reaction.
This rate constant is believed to be known within a factor of two (Reference
6-I).
The temperature chosen for obtaining qualitative agreement with Cookson'sresults was about IlO°R, or 5 percent lower than the unmixed air inlet static
temperature. This is not considered a serious discrepancy in view of the
assumption of premixing in the model and the uncertainties in the chemicalkinetic rate constants.
It is believed that the qualitative agreement between theory and experi-
ment in this case is sufficient to indicate that the O.75-deg divergence of
the combustor used by Cookson et al. may have had a serious effect on the
chemical kinetics_ leading to the observation of little or no burning insidethe combustor.

6.2 CHEMICAL KINETIC SIMULATION OF TWO-DIMENSIONAL COMBUSTOR TESTS
Combustion tests were conducted with a two-dimensional 3 constant-width
combustor having a length of 29 in. 3 an inlet cross section of 0.6 by 6 in. andan exit-to-inlet area ratio of 2.6. The tests were conducted at various test
temperatures and injector geometries. Fuel was injected in two stages; the
first in a constant area 3 the second in a diverging area as shown in Figure
6.2-I. High chemical efficiencies were obtained in the first stage (about 90
percent) while second-stage efficiencies were lower (about 60 to 70 percent).
A study was made to determine if the second-stage combustion was chemical-
kinetics }imited or mixing limited. The Zupnik computer program (Reference
3-I) was used in the second-stage combustor to investigate the chemical kineticsj
and the Frey computer program (Reference 2-2) was used to investigate both
chemical kinetics and mixing in the first- and second-stage combustors.
The first case studied was at a test total temperature of 3000°R with
¢ = 0.68 injected in the second stage. Entrance conditions to the second stage
were calculated from a one-dlmensiona] data reduction program using equilibrium
chemistry. In this case 3 second-stage entrance conditions were determined
assuming complete combustion in the first stage.
The Zupnik computer program (Reference 3-1) was used to evaluate second-
stage combustion. The calculated air static temperature (from the data reduc-
tion program) was averaged with the 1500°R H 2 temperature and resulted in a
2100°R mixed fuel-alr temperature at the second stage entrance. Results in
Figures 6.2-2 through 6.2-4 indicated no second stage combustion. The OH
concentration reached a maximum of 1.47 x I0"B moles/liter or about I00 times
lower than that used to indicate ignition delay_ Figure 6.2-4.
Two cases at 3800°R total test temperature were run in a manner similar
to that at 3000°R. This time an equivalence ratio of 0.25 was injected in the
first stage and _ = 0.38 and 0.78_ respectively3 were injected in the second
stage. Results are shown in Figures 6.2-5 and 6,2-6. In both cases 3 the fuelstarted burning about I-in. from the second-stage entrance.
The static temperature distribution computed for complete mixing was
higher than that calculated from the data reduction program. This hi9her
temperature arises because more fuel reacts as shown by the chemical efficien-
cies in Figure 6,2-7. AIso_ cooling losses are not accounted for. The maxi-
mum reaction rate occurred (Figure 6.2-7) at a point about 2-in. downstream
of second-stage injection, a chemical efficiency of 80 percent was attained
5-in. from injection. Several species are plotted in Figures 6.2-8 and 6.2-9
for the stoichimetric and fuel lean cases, respectively. In both cases there
was a rapid increase in the concentrations of H 30_ OH and HO2. About 1,5 to
2.5 in. downstream of injection the production rate of OH3 HO2 and H began to
decrease.
Therefore with the assumption of complete and instantaneous mixing and no
second-stage air-fuel injection disturbance_ the second stage fuel reacted

rapidly at 5800°R total temperature and did not react at all at 3000°R total
temperature. At 5800°R about 80 percent of all fuel injected reacted which
was higher than that calculated from the one-dimensional data reduction program.
A more realistic study atboth temperatures was made With another computer
program. Measured static pressures_ cooIing_ mixing_ and friction losses were
included in the model. The results of that study follow.
Two of the two-dimensional combustor tests were simulated in the Shear
Layer Combustion Computer Program (Reference 2-2) developed by Dynamic Science.
This program permits the analysis of complex chemical kinetic systems with
arbitrary gas phase reactions and species using a one-dimensional (area or
pressure defined) stream-tube model. Unique features of this program are (1)
its ability to integrate the differential equations governing the chemical
kinetic system with complete numerical stability using an implicit integration
technique (Reference 6-2)3 and (2) its ability to add (or extract) mass momen-
tum_ energy 2 and species at any position along the stream tube.
The simulation of the tests was based on the assumption of two limitingconditions. The first of these conditions assumed that the combustor effi-
ciencies calculated from test data represented chemical efficiencies (100percent mixing efficiency). The second assumed that the combustor efficiencies
represented the mixing efficiencies.
The several mixing models used with the two limiting conditions were
implemented by the concept of an inert hydrogen molecule denoted by the symbol
HZ 2. This inert hydrogen molecule participated in the flow dynamics_ but
was not permitted to dissociate or react with other species. Mixing was done
by replacing inert hydrogen (HZ 2) with active hydrogen (H2) using the species-
addition feature of the computer program.
The three basic mixing models are shown in Figure 6.2-10. Model I pro-
duced early mixingj Model 2 produced a maximum mixing rate at the mid-point
of the mixing length_ and Hodel 5 produced late mixing, Further variationwithin each mixing model was obtained by varying both the mixing length and
the amount of hydrogen mixed at the injectors.
The two tests chosen for this simulation are listed in Table 6.2-1 along
with their nominal test parameters.

The chemical kinetics calculations were started at Station 7.3_ just ahead of
the first stage injectors_ using equilibrium concentrations of the species.
The energy and momentum defects due to heat transfer and wall friction were
distributed linearly along the combustor_ While the energy_ momentum 3 and mass
addition due to fuel injection were input at the appropriate injectors. The
pressure-defined stream tube model was employed using measured static pres-
sures from the two tests (see Figure 6.2-11).
The results obtained from imposing the two limiting conditions on the
simulation of run 258 in the Shear Layer Combustion Computer Program are pre-
sented in Figures 6.2-12 through 6.2-14_ where the areasj mixing efficiencies 3
and chemical efficiencies were plotted as a function of axial position. In
all cases I00 percent mixing efficiency (_m) was assumed in the first stage
combustor using mixing model 2 with 50 percent mixing at the injectors and
complete mixing at station 12. Examination of the calculated areas in
Figure 6.2-12 indicated a reasonable blockage (50 percent) in the constant-
area portion and reattachment of the flow near the entrance of the divergent
portion of the first stage combustor. The first stage results demonstrated
chemical efficiencies of 95 percent at station 13 and nearly lO0 percent
beyond station 17 (see Figure 6.2-14).
The first limiting condition (I00 percent overall mixing efficiency) was
imposed on the second-stage combustor using both a 50-percent local mixing
efficiency at the injectors with mixing Model 2 and a 0 percent local mixing
efficiency at the injectors with mixing Model 5. An overall mixing efficiency
of I00 percent was set at station 29 with both mixing models-- the former
simulating early mixing; the latter_ late mixing.

Examinations of the calculated areas (symbols + and 0) in Figure 6.2-12indicated a reasonable blockage (15 percent) at the second-stage injectors 3however both mixing models eventually required flow areas greater than thegeometric areas. Since such flows would be impossible to attain with themeasured pressures from run 258_ the assumption that the combustor efficiencyequalled the chemical efficiency with IO0-percent mixing was in error. Thisargument was further substantiate_ from the chemical efficiencies in Figure6.2-14 where values were 92 percent for early mixing and 82 percent for latemixing_ compared with the value of 60 percent required to match the test data.
Therefore 3 the other limiting condition (combustor efficiency = mixingefficiency) was imposed on the second-stage combustor. A 50-percent localmixing efficiency at the injectors with mixing Model I (early mixing) wasassumed. An overall mixing efficiency of 60 percent was set at 4.0- and 8.2-in. downstream of the injectors (second stage) as shown in Figure 6.2-13.
Again 3 as shown in Figure 6.2-12, the calculated flow areas indicated areasonable blockage in the vicinity of the second-stage injectors, with theblockage gradually decreasing to zero as the flow approached the combustorexit. The mixing length of 4 in. produced flow areas which closely matchedthe geometric areas and resulted in a chemical efficiency of 97 percent.
The two limiting conditions were imposed on the simulation of run 242using the same mixing models as in run 238 with the exception that time didnot permit the late mixing case to be run. The flow areas, mixing efficien-ties 3 and chemical efficiencies were plotted as a function of axial distanceand presented Ln Figures 6.2-15 through 6.2-17. Examination of the areas inFigure 6.2-15 again indicated that the first limiting condition (chemicalefficiency = combustor efficiency, I00 percent mixing) was in error and thatthe flow areas resulting from the second limiting condition more closelymatched the test conditions. The fluctuating flow areas near the exit of thecombustor (Figure 6.2-15) were due to pressure fluctuations (see Figure 6.2-10).
While it appeared that the second limiting" condition_ i.e._ incompletemixing produced the correct flowfields_ the true condition could be foundsomewhere between the two limiting conditionsj quite close to the second. If
the chemical efficiency is denoted by _c combustor efficiency by _ and, mixing

could be used to iterate on a mixing efficiency to produce flows which would

The results from the above test simulations support the conclusion that
the low combustor efficiencies experienced in the two-dimensional combustor
tests were due to poor mixing in the second stage.
The detailed results from the chemical-kinetic simulation of runs 258
and 242 are presented in Appendixes I and 2.

7. AIM ENGINE
7.1 ANALYSIS
In the AIM combustor_ fuel is injected from several locations as
shown below: Ib i
Ic 2cla
/
The first stage injectors (la_ and Ib) are located in a slightly diverging
section; the second stage injectors (Ic3 4 and 2aj 2c) at greater divergence.
Fuel flow requirements in the first stage are set to prevent inlet unstart
and thermal choking. The second stage fuel flow schedule was to be determined
from cycle analysis and mixing studies.
A simulation of both stages was made in a two-dimensional combustor
test. Testing demonstrated high chemical efficiency (near 90 percent) for
the first stage injectors. The second stage injectors_whlch were located
in a diverging area_ gave much lower efficiencies (near 60 to 70 percent).
A study was made of the present AIM combustor to see if these low efficiencies
were inherent in the design due to chemical kinetics.
It was assumed that combustion would be temperature-controlled. Thus
complete mixing was assumed. The Zupnik computer program was used to de-
termine whether the second stage combustor could have a high chemical
efficiency.
The first case studied was Math 7 total temperature at I000 psia total
pressure to simulate test conditions for Future AIM tests. It was assumed
that an equivalence ratio of 0.4 would be injected from the first stage
and that the second stage would begin midway between injectors 2a and 2c.
A chemical efficiency for the first stage was based on two-dimensional tom-
buster test results which indicated that at ]east 80 percent chemical el-
ficiency should be obtained in the first sta9e combustor at an equivalenceratio of 0._.
The engine cycle program was used to determine second-stage entrance con-
ditions. This program uses equilibrium chemistry. Using the output static
_J AIRESEARCH MANUFACTURING COMPANYLo__NI_ C=k_
70-6519
Page 7- I
temperature from the engine cycle program and assuming 900°R H2 fuel at an
equivalence ratio of 0.6 gave a mixed fuel-air temperature of 5000°R. This
H2 temperature included second stage cooling losses. Using this mixed tem-
perature at 19 psia and 4800 ft/sec as the first stage exit conditions, the
static pressure and temperature profiles for the second stage combustor were
calculated in the Zupnik chemical kinetics program as shown in Figure 7.1-I
and 7.1-2. Examination of these profiles indicated a very short ignition
delay period at mixed temperature of 3000°R. At a distance of 2.7 cm down-
stream of the second-stage entrance, the flow thermally choked after 85 percent
of all fuel injected in both stages (¢ = 1.0) had reacted. Instantaneous
complete mixing was assumed at the second stage entrance. Actually, mixing
will take some finite length with mixing and reaction occurring simultaneously
over a portion of the combustor. Therefore_ whether choking would actually
occur cannot be determined using this model. However, with the assumption of
complete and instantaneous mixing it does appear that at Mach 7 conditions
there will be no chemical kinetics problem in the second stage combustor of
the AIM engine. When the first stage chemical efficiency was reduced to
50 percent, which produced a mixed temperature of 2_O0°R, the fuel reacted
less rapidly as indicated in Figure 7.1-2. In this case, a chemical ef-
ficiency of 83 percent was attained at a distance of 8.3 cm from the second
stage entrance. Since the Mach number was about 1.6 at this point_ it is
improbable that thermal choking would have occurred had the calculation been
continued.
Combustion occurred when species H and OH produced from first stage com-
busion were removed at the second-stage entrance (see Figure 7.1-2). There
is, howeve_ a |arge ignition delay with about 53 percent of the second-stagefuel reacted 19.2 cm from the entrance. This case is not very realistic_
but was conducted to demonstrate that 3 at Math 7_ there is no combustion
problem due to temperature alone.
An idea of how the mole fractions of several species varied with combustor
length is presented in Figures 7.1-3 and 7.1-4. At a mixed temperature of
3000°R (see Figure 7.1-3) the concentrations of H, O, OH and HO 2 increased
rapidly, but after I cm the concentrations of H, O, and HO2 decreased. The
buildup of OH and H20 became less rapid after I cm, and OH started to de-
decrease just before thermal choking occurred. Similar trends were observed
at a mixed temperature of 2_O0°R (see Figure 7. l-L). It appeared that the
production rate of H20 started to decrease at 6 cm of combustor length and
that the reaction of H2 proceeded very slowly beyond 7 cm. In the AIM com-
bustor there is about 5-times as much length compared with the two-dimensional
combustor so slower reaction should not be a problem. The variation of second
stage chemical efficiencies are shown in Figure 7.1-5. The chemical efficien-
cies were approximated from the change in weight fraction of H2. This is not
exact since even if the chemical reaction were to go to equilibrium3some H2
would remain. It does indicate, though_ a rapid increase In chemical ef-
ficiency near 80 percent with a slow rise thereafter.

The second case simulated Mach 6 flight conditions. The manner in which
the study was conducted was the same as at Mach 7. This time an equivalence
ratio of 0.2 was assumed For the first stage with a chemical efficiency of 80
percent at a point midway between injectors 2a and 2c. The second-stage
equivalence ratio was 0.8, and several fuel temperatures from 900°R to I500°R
were used. The results obtained from the finite kinetics program are shown in
Figures 7. I-6 and 7.1-7. At a fuel temperature of 900°R_ the mixed fuel-air
temperature was 2150°R and no temperature rise was observed; at I500°R fuel
temperature or 2270°R mixed fuel-air temperature the fuel burned rapidly.
A mixed temperature between these two was run (2200°R) and in this case the
fuel also reacted. Thus using species concentrations based on equilibrium
chemistry for second-stage entrance conditions showed that a change of 50°R
mixture temperature would produce a go or no-go situation. When the H and OH
produced from the first stage combustion were removed at a mixed temperature
of 2200°R, no temperature rise was observed_ as shown in Figure 7.1-7. This
was not the case at Mach 7 at a mixed temperature of 2400°R. At a mixed tem-
perature of 2270°R, about 70 percent of all fuel injected (_ = 1.0) reacted
before thermal choking occurred, while at 2200°R mixed temperature 60 percent
reacted before computer cut-off time was reached (flow did not choke). The
chemical efficiencies for these cases are shown in Figure 7.1-8. When the
fuel reacted it did so rapidly. The chemical efficiencies continued to rise
at both mixed temperatures.
Several species were plotted in Figures 7. I-9 to 7.1-12 for cases with
fuel reacting and without fuel reacting. The OH concentration for a mixed
temperature of 2150°R reached a maximum of 2 x I0"7 moles/liter at about 6 cm
downstream of the second stage injection as shown in Figure 7.1-II. At this
point the static temperature had dropped to about 1950°R with a static pressure
of 20 psia. The parametric studies seemed to indicate that once the static
temperature became less than about 2000°R in a divergent duct and the OH con-
centration had not reached I0-6 moles/liter by then, combustion did not occur.
Thus, results from chemical kinetics simulation of the AIM configuration were
consistent with the parametric study in Section 3 of this report. For the
cases with combustion(Figures 7. l-9 and 7. I-10) an OH concentration of #0-6
moles/liter was always reached before the static temperature was reduced to
2000°R. As shown in Figure 7.1-12, the 50°R difference in static temperature
between the go and no-go cases caused an increased production rate of OH start-
ing at about 0.05 cm from the second stage entrance. Thus the OH concentration
was able to reach 10-6 moles/liter before the temperature became too low due to
divergence.
For a mixed temperature of 2200°R, an OH concentration of 10 -6 moles/liter
was reached in about 3 cm. This corresponded to an iqnition delav time of
about 25 _sec. By this tlme the temperature had dropped to 2100°R.. If one
had assumed expansion with friction at a mixed temperature of 2150°R, the
variation of static temperature with time would have been as shown in Figure
7.1-13. With a friction coefficient of 0.006_ at 25 _sec, the static temper-
ature would be close to 2100°R. Thus_had friction been included in the modeI_

combustion at a mixed temperature of 2150°R would probably have occurred.
Also 3 the model did not Include any temperature rise from fuel disturbance
which would have helped initiate combustion.
The above study indicated that second stage combustion was very sensi-
tive to the first-stage chemical effic!ency_ fuel temperature 3 and skin friction.
Second-stage entrance conditions (including the concentrations of ali
major species) were determined from an engine cycle program which used equilib-

of a chemical kinetics solution in both stages would affect the combustion
characteristics of the second stage. The results showed that iE would.
The first-stage entrance static temperature at Mach 6 is about 1300°R.
At this temperature the finite kinetics program would indicate no combustion,
To simulate the air shock due to fuel injection_ an air static temperature of2000°R was chosen as the first stage entrance condition. An equivalence ratio
of 0.2 was assumed and combustion at a constant area was specified to insure
that the fuel would react. In this manner it was hoped that at the same amount
of fuel reacted (in a constant area)_ static temperature_ pressure and velocity
would match that from the engine cycle computer program, Thus the only dif-ference in second stage entrance conditions (if any) would be the concentration
of the individual species.
The first stage was defined to be halfway between injectors Ic and 4 at
a chemical efficiency of 50 percent. With 900°R H2 fuel_ the mixed fuel air
temperature was 1800°R. As shown in Figure 7.1-14_ reaction took place al-
most immediately_ and the flow choked about I cm downstream of injection.In this case the initial concentration of OH at the entrance of the second
stage combustor was 3 x 10 -5 moles/liter_ or 30-times that concentration used
to define the ignition delay time. This OH concentration was also I00 timesthat obtained from the cycle program output which used equilibrium Ehemistry
(Figures 7.1-9 to 7.1-12). As shown in Table 7.1-1_ the values of carriers
O_ H_ HO2 and H202 also changed significantly.
Therefore with finite rate kinetic chemistry_ second stage combustion
occurred at a mixed temperature of 1800°R_ whereas with equilibr|um chemistry
a mixed temperature of 2200°R was required for combustion. This indicated
that at Hach 6_ second stage combustion would not be chemical kinetics-limited.Thus at both Hach 6 and 7 there should be no combustion problem if complete
mixing is assured.
Since combustion was shown to be very sensitive to initial specie con-
centration_ an investigation was made varying the percent of fuel reactedin the first stage in order to determine the effect on combustor length. To
simplify results the first stage was run at constant area and the second stage
at a constant divergence. An equivalence ratio of 0.2 was used in the first
stage at 2000°R_ 20 psia and 4400 ft/sec mixed conditions. An equivalenceratio of 0.8 was used for the second stage. The effect of varying the per-
centage of first stage fuel reacted on combustor length is shown in Figure 7.1-15.

In a length of I0 cm, 2 percent of the first stage fuel reacts while it takes
about 18 cm for 97.8 percent of the fuel to react. Mixing the temperature of
output alr with 5&O°R fuel shows that about 25 percent of the first stage fuel
must react in order for combustion to occur in the second stage at a divergence
(dA/AldX) of 0.03 cm"I. No combustion occurred in the second stage for values
of less than I0 percent of fuel reacted in the first stage. However_ the
overall combustor length does not necessarily decrease as the percentage of first-
stage fuel reacted increases. The reason is that first stage combustor length
increases much more rapidly than the second stage length. This is more clearly
shown in Figure 7.1-16. In fact a minimum occurs near 60 percent of first stage
fuel reacted. The overall length is shown at a constant H2 mole fraction of
0.15 or at a constant overall chemical efficiency of about 55 percent. This
efficiency was the highest reached without choking the second stage with 97.8
percent of fuel reacted in the first stage. A similar minimum occurred when
the divergence was doubled to 0.06 cm -I (Figure 7.1-17). This indicated that
making the first stage of the combustor less efficient might decrease the
overall combustor length.
In summary,
(=) Equilibrium chemistry and finite kinetics chemistry in the
first-stage combustor did not predict the same combustion
characteristics for the second stage of the AIM combustor.
(2) Finite-rate chemistry assuming complete mixing indicated
no second stage combustion problems at both Mach 6 and 7.
(3) Shorter combustor lengths might occur with less efficient
first stages.
7.2 AIM KINETICS AT MACH 6
Model T inlet test data indicate that at Mach 6 the static temperature
for undisturbed flow at the first injecti.on station of the AIM will be
approximately 1290°R, the local Mach number being about 2.8. This static
temperature is too low for autoignition. Some exploratory chemical kinetic
calculations were made_ using the Shear Layer One-dimensional Combustion
Program, (Reference 2-2) to ascertain what strength of flow disturbance might
be needed at the first injection station in order to initiate combustion. A
further calculation was made for the second stage with no flow disturbance
other than that from simple mass and energy addition (no boundary layer sep-aration).
For all these calculations certain constant conditions were assumed.
The first-stage total equivalence ratio was set at 0.2, the fuel being
equally split between the two first stage injectors (la and Ib). The second-
stage total equivalence ratio was 0.83 split equally between _njectors 2c
and 2a. The igniters, about I in. downstream of the first-stage injectors,
were assumed to contribute 0.0413 lb/sec of hydrogen-oxygen combustion products

at an overall igniter equivalence ratio of 1.6. The igniters' combustion
efficiency was taken to be 23 percent_ giving a mixed igniter exit gas tem-perature of 3050°R. The composition of the igniter gases was taken from quasi-
equilibrium calculations using the above chemical efficiency.
A uniform frictional force of 18.7 Ibf/in. along the combustor's length
was assumed. Estimated local heat losses were used; these varied between I09
Btu/in. sec. and 234 Btu/in. sec. and were specified as a function of axial
distance.
The fuel temperature was assumed to be 1440°R, and the total air flow was
taken to be 34.6 lb/sec. The fuel and the igniter gases were assumed to be
injected normal to the engine axis_ and to mix completely and instantaneouslywith the main flow. The fuel was injected over a length of 0.2 inches at each
injector.
The disturbances assumed for the flow ahead of the first injection station
corresponded roughly to those produced by two-dimensional flow over a wedge.
Thus the strength of the disturbance can be described by specifying a wedge
angle.
Results
Assuming a 15-deg wedge angle ahead of the first injection station gave
a Mach number of 2.1i a static pressure of 47 psia_ and a static temperature
of 1740°R just upstream of the first injector. An effective flow area reduction
of 47 percent was used in order to satisfy continuity. In the first calculation
using these conditions_ the effective flow area was kept constant for a distance
of 2 in._ then linearly increased to the actual duct area at.a point 8 in. down-stream of the first injector. Fuel injection and igniter gas injection pro-duced static temperature rises in the constant-area section (see Figure 7.2-1),
but the maximum temperature was less than 1800°R. Ignition did not occur.
The computed pressure profile is shown in Figure 7.2-2, and Figure 7.2-3 shows
the concentration of OH.
A second calculation was made using the same initial conditions but with
the assumption that the pressure along the combustor was constant. In this
case fuel injection produced a slight drop in static temperature, and theeffect of the igniter on static temperature was negligible (see Figure 7.2-4).
Again, ignition did not occur.
Increasing the wedge angle to 20 deg gave an initial static temperature
of 1940°R, a pressure of 61.7 psia 3 and an effective area reduction of 51
percent. A chemical kinetic calculation using constant pressure indicatedcomplete combustion in the first stage. The temperature profile is shown in
Figure 7.2-5. The area expansion of the gas stream at the equivalence ratio
of 0.2 (see Figure 7.2-6) was not sufficient to fill the actual cross-sectionalarea of the AIM duct. Consequently_ the calculation was re-started at a point
near completion of first stage combustion (Z = 45; see Figure, 7.2-5). From
this point on_ an assumed effective flow area (rather than constant pressure)
was specified. The initial area was that determined by the first stage constant

pressure calculation; the effective area was then increased linearly unti| it
matched the actual duct area just downstream of the first injector of the
second stage. At the entrance of the second stag% the computed gas temperaturewas over 2300°R. The calculatlon indicated that the Fuel from the first
injector of the second stage would burn in a very short distanoe and cause
choking of the flow.
7.3 DISCUSSION
Time ]imitations prevented the investigation of any mixing model other
than instantaneous mixing for the AIM. With respect to the mixing model, the
calculation must be considered optimistic. Also, it is not known whether any-
thing approximating a constant-pressure profile can be sustained over a length
of 4.5 in. in the AIM's diverging first stage geometry.
The strength of the flow disturbance (pressure ratio of almost 4 to I)
required to produce combustion in the theoretical calculations is probably
excessive; it is unlikely that this pressure ratio can be induced in the AIM
(at some equivaIence ratio) without unstarting the inlet. However, it may be
possible to initiate combustion with smaller disturbances because of localized
igniter effects.
Treating fuel and igniter gas injections one-dimensionally undoubtedly
neglects some of the most beneficial effects of these processes. The igniter
gases, for instance, are known to be poorly mixed; the igniters' design is in
Fact based on film cooling by unmixed oxygen. The core of the igniter streams
therefore contains zones which have higher temperatures, and correspondingly
higher concentrations of labile species, than indicated by the fulIy-mixed
igniter model.
The effectiveness of the igniters is also considerably increased because
the hot gases mix only with part of the mainstream. The assumption used in
the calculations, namely that mainstream gas is mixed with igniter gases in
a mass ratio greater than 800 to I, leads to the unrealistic result that the
igniters' effect on local static temperature is negligible. For Mach 5 test
conditions the igniter used in the two-dimensiona] combustor was effective
with a static temperature (before boundary layer separation) of approximately
lO00°R. The undisturbed static temperature in the AIM is 1290°R; hence, it
seems possible that combustion can be initiated in the AIM by use of the
igniters even if the flow disturbance is small. Als%the prediction of choking
at the second injection station might be negated by use of a reasonable Finite-
mixing model.
The conclusion from this AIM study is that with instantaneous mixing and
for the conditions assumed in the 20 deg wedge angle case, the second stage of
the AIM would not be klnetically limited at the Mach 6 test condition.

8. DISCUSSION AND RECOMMENDATIONS
8,1 DISCUSSION
The analytical studies have indicated that chemical kinetics problems
wou]d not be present in the AIM engine at Mach 6 and 7 f]ight conditions.
Inadequate mixing was considered to be the major contributing factor for thelow combustor efficiencies in the two-dimensional combustor tests. In order
to substantiate these theoretical findings, it is recommended that future
research programs be directed to better understanding the mixing process, par-
ticularly in a confined, favorable pressure gradient system.
As discussed in the fifth oral review_ Reference 8-1j the mixing process
in a supersonic combustor may be classified in three distinct phases; (I) jet
penetration, (2) turbulent mixing, and (3) molecular diffusion. Among these,the turbulent mixing is least understood. The function of jet penetration is
to properly distribute the fuel sources into the combustor by means of jetmomentum. The turbulence either existing in the airstream or generated by jet
penetration and combustion is to break up the fuel sources into many small
lumps stirring up the fuel and air. Finally3 mixing is completed by moleculardiffusion which brings hydrogen and oxygen molecules into intimate contact.
The molecular diffusion process is slow_ therefore, in order to shorten the
mixing length, it is necessary to generate strong turbulence and small eddiesat the molecular level to reduce the distance in which the molecules diffuse
for complete combustion.
Since turbulent mixing theory is still in an early stage of development_it cannot be applied to the solution of this problem at present. Therefore,future solution of this problem will have to rely on experiment.
8.2 FUTURE WORK RECOMMENDATIONS
The following items are recommended for future work to extend and com-
pliment present efforts in solving potential problems in supersonic combustion.
8.2.1 Analytical Approach
The analytical study may be best summarized by Swithenbank's paper,Reference 8-2. In general, the low-wave-number end of the turbulent energyspectrum depends on the geometry of the turbulence-producing device, while thehigh-wave number region of the spectrum is almost isotropic and independentof the source of eddy formation. The smalier eddies are very important in theturbulent mixing process in which two gases are stirred together, to the mole-cular level. Since the high-wave-number eddies contain about 80 percent of thetotal turbulent energy J the ability of different systems to achieve mixing

will depend largely upon the total turbulent energy in each particular system.
In general 3 the ability of a turbulent mixin 9 system to mix two gases willdepend upon
(a) Intensity of turbulence
(b) The scale of turbulence
(c) Mixing region length
(d) Lateral distances through which the injected fluid must travel
(e) Velocity of gas through the mixing system.
To obtain a semi-quantitative analysis of the mixing process 3 we need to
know the relation between these five various quantities 3 and the effect of
the chamber 9eometry.
The analytical study should provide guidance in conducting a well defined
experimental effort.
8.2.2 Experimental Approach
The fuel mixing process is strongly influenced by the levels of intensity
of turbulence. The one-dimensional chemical kinetics program has indicated
that the separation bubble in the first stage is in the order of 30 to 40 per-
cent of the duct area, while in the second stage 3 only 15 percent of flow
area is blocked. This points to a low level of turbulence, and poor mixing in
the second stage. General Electric's Report_ Reference I-I_ stated: "The
constant-area section provides maximum pressure disturbances for given fuel
injection and burning; a necessary situation if high-Mach efficiency is to be
9ood". Since the quoted statement was based on experiments 3 no detailed
explanation was given in that report. The static pressure distributions fromthis test are reproduced in Figure 8.2-1 for reference. The implication was
two-fold. First because the "high-Mach" referred to was Mach 9.53 where burner
inlet static pressure and temperature were approximately 4.8 PSIA and 2500°F
respectively_ the chemical kinetic problem was absent. The calculated ignitionI dA
delay time was at most 50 _sec; The divergence parameter _- _ was 0.0139-I
am at the initial point. Second_ because of the high static temperature_the static pressure rise due to combustion is lower; this results in less flow
separationj less turbulence and poorer mixing. The latter is considered tobe the basic problem in future high-Mach number flight conditions.
In view of the above discussion_ the future research program should be
directed toward the following:
(a) To correlate turbulence produced by external sources with mixing 3
such as the effects of boundary layer thickness_ shock strength_
size of separation bubble 3 combustor 9eometry_ pressure gradient and
combustion. Particular emphasis should be placed on a confined
geometry with favorable pressure gradients.

(b) To develop a turbulence generation method. Swithenbank argued that
the distance to generate turbulence in a swirling jet is about I/3
the distance required by a nonswirllng jet. Furthermore 3 the intensity
of the turbulence in the developed region is higher in a swirling
jet 3 because for a given axial velocity of the jet there is an
additional tangential velocity representing an increase in the jet
kinetic energy.
(c) One of the difficulties in experimental work on turbulent mixing is
the accurate measurement of the mixing process. The measured quan-
tities are averages of the instantaneous values because the turbulence is a
random 3 fluctuating flow and the flow is three-dimensional. The mixing is not
as complete as that indicated by the time-averaged measurements taken over a
period of time using a gas-sampling probe. The sampling probe mixes rich and
lean regions to indicate an average composition. This may explain the low
combustor efficiencies in the two-dimensional combustor tests 3 in which gas-
sampling measurements indicated uniform mixed flow at the exit. This phenom-
enon was also reported in Reference 8-3 and requires further exploration.
8.2.3 Methods to Improve Mixing
A sudden rearward-facing step in a combustor will promote mixing, how-
ever 3 it would result in lower pressure forces on the combustor wall. In
other words_ the rearward-facing step will produce higher chemical efficiency3
but lower total pressure. The tradeoff between these two should be closelyexamined.
At high-flight Mach numbers where thermal choking is not likely to occur_a converging burner which would enhance flow separation cannot be ruled out asa potential solution.
The effects of surface roughness were clearly demonstrated in the Phase
I boilerplate engine. In the paper presented at the 3rd AIAA Propulsion
Specialist Meeting_ it was stated that "The Hastelloy-X-coated engine demon-
strated quite different characteristics from the pure nickel-coated engine."
The high pressure at the fuel injection station indicated spontaneous combus-
tion 3 the flow was nearly chokedj the ignition temperature was lowered about
300°F and the slope of the pressure curve was much steeper. This phenomenon
may be due to a combination of the effects of (I) the higher surface tempera-
ture_ (2) the increased thickness of Hastelloy X coatingj which reduces the
flow area and increases the static pressure and temperature, (3) the greater
area contact with the airstream of the Hastelloy X, which contains 50 percent
nickel 3 and (4) turbulence produced by the rough surface coating. In order to
further examine these effects 3 the surface was smoothed from the throat to a
distance approximately 12 to 14 in. downstream of the throat. The test results
indicated that there was no significant difference between the rough- and the
smooth-surfaced engines. The smoothed surface was later verified by laboratory
check as having an average roughness of 300 microinches.
Examination of the methods discussed above indicates the surface coating
to be most adaptable to the AIM engine.

9. CONCLUSION
The results of this study lead to a number of conclusions with regard to
chemical kinetics in a supersonic combustor. One broad conclusion obtained
is that chemical kinetics is very sensitive to the divergence of the combustor.
Basicaliy_ this is attributed to the low stream static temperature which
"freezes" the species in a manner very similar to that in nozzle flow.
The detailed chemical-kinetic simulation of the HRE two-dimensional com-
bustor test results indicated that low combustor efficiencies in the second
stage were due to mixing. In the extreme case of late but complete mixing 3 the
chemical efficiency approached 82 percent which indicated that the second-stage
flow was not overly kinetics-limited due to the decreasing temperature in thedivergent duct.
For the AIM engine at Mach 6 flight conditions_ with second-stage fuel
injected at,stations 2a and 2c; calculations indicated that combustion was
not chemical-kinetics limited. Assuming that the fuel was completely mixed
with air at the injection station3 the second-stage flow was choked.
