PENGEMBANGAN PERSAMAAN POROSIT AS DAN ERGUN PADA UNGGUN FLUIDISASI TIGA FASA

Behavior of liquid-solid fluidized beds has been studied based on hydrodynamic characteristics. The hydrodynamic aspects include pressure drop, fluidization condition, porosity and height of expanded bed with various liquid velocity and particle size of quartz sands or glass bead Empirical correlation to predict the bed porosity for various superficial velocities developed based on particle resistant model .. Experiment conducted in a glass column with diameter of 9 cm and height of 150 em. The result showed that the relation of pressure drop, fluidization condition and expanded bed porosity with superjicial liquid velocity depend on particle size and shape. Based on dimensional analysis the relation between bed porosity and superficial liquid velocity could be correlate
