Abstract

To perform an experimental study of the hydrodynamics of FLUIDIZED BED and investigate the affecting parameters, a FLUIDIZED BED has been designed and fabricated. This bed consists of 212 to 800 microns silica sand in a transparent vertical cylinder with 14 cm inner diameter. It is fluidized by air at atmospheric pressure and temperature. In this research, at first the minimum FLUIDIZATION velocity for different sand sizes and bed heights are obtained. Then the effects of size and height on the pressure drop across the bed have been studied. Finally, the experimental results are compared with calculated values from existing correlations to determine the deviations of the predicted values. Results indicate that by increasing the particle size in the equal bed height, the minimum FLUIDIZATION velocity is increased, while the pressure drop does not significantly change. Also, by increasing bed height, the pressure drop is increased, while increase in the minimum FLUIDIZATION velocity is ignorable. Also, BED PRESSURE DROP changed linearly with bed height.
