Transport Phenomena
Wim Brilman2018
Transport Phenomena: … mainly deals with non-equilibrium situations
differences lead to transport of mass, momentum, energy…
the rate at which these processes proceed is a typical objective
Fluid dynamics further includes calculation of forces,
momentum, velocity and -profiles and pressure drop
In this course : Fundamentals of transport of momentum, mass and energy
are introduced and applied, aiming to
understand and (quantitatively) describe phenomena
encountered in industrial/engineering practice and in daily life.
The course is integrated with the course Numerical Methods, in which modeling skills (in MATLAB) are developed and applied to mentioned situations.
Typical Transport Phenomena…

PRACTICUM PROJECT
About Practicum and Project
Practicum: * experimental study of heat or mass transfer processin an engineering-type set-up
* well-defined set of experiments* team of 2 persons* guidance & preparation session with supervisor* small report (typical 10 pages; including prep. work)
Project: * work in teams of 4 persons + coach/consultant* project assignments: selection from list* challenging project: outcome is unknown* problem analysis = group-work* making a plan and carry it out
* experimental work* modeling
* reporting (written report + presentation)
EXAMPLE PROJECT: FOOD DRYING
For large scale production of fries, freshly cut potatoes must be partly dried to increase the dry matter content from (around) 18% to(around) 25%. This is done in industrial dryers.
For product quality a careful control of the drying process is needed. A good model wouldcertainly be an assett here.
Objectives are
• Make a model for an industrial dryer
• Determine the drying rate experimentallyand compare it with your model
heating
Geometry of potato fries Effect of relative humidity Combined heat and mass transfer Design your own experiments

After this module you should :
* have knowledge of the basics of transport phenomena
* be able to recognize transport processes and make link theory practice
* be able to formulate the transport processes into a model description
* be able to solve these problems numerically & analytically (where possible)
