GLOBAL JOURNAL OFENGINEERINGSCIENCE ANDRESEARCHES PREDICTION OF BED PRESSURE DROP AND TOP PACKED BED HEIGHT IN THREE PHASE SEM-FLUIDIZED BED OF REGULAR HOMOGENOUS TERNARY MICTURES

Hydrodynamics of gas-liquid-solid semi-fluidized bed relating to packed bed formation and bed pressure drop with regular homogeneous ternary mixtures, have been studied in a 0.05m internal diameter Perspex column, with water and air (secondary) as fluidizing medium. Experimental parameters studied include superficial gas and liquid velocities, average particle size and static bed height and the bed expansion ratio. Empirical and semi-empirical models have been developed. The calculated values from predicted models have been compared with the experimental values and fairly good agreement has been obtained. The hydrodynamics study conducted and the correlations developed thereof can find potential applications in physical and chemical processing
