ABSTRACT

In the work presented in this experiment, the behavior of fluidization of

fine sand was studied. The different air flow rate supplied to the system and its effect

on the characteristics of fluidized bed such as thickness and the condition of

fluidized bed formed was investigated. Expected behavior has been found in this

experiment in relation to the pressure drop and air flowrate as confirmed with Ergun

equation (Pressure drop increase with the increasing of air flowrate). It was found

that the fluidization point of the sand bed is 315 mm H 2O and the air flowrate is

11.53 cm/s while the porosity value of the particle layer is 0.2335. The behavior of

sand acting like a fluid and start to burst - a big gap of the fine sand in the tube was

observed when air flowrate exceeds 11.53 cm/s. Apart from that, at the fluidization

point, friction force between solid particle and fluid would be offset between each

other, thus resultant force between particles was neglected and pressure drop was

identical
