✦ Synopsis

Harrison and Leung model for spherical bubble formation in fluid&d beds has been extended to account for the dynamics of the emulsion phase. The simplified Davidson-Harrison model is used to obtain the gas and particle velocities in the emulsion phase sad includes the effect of the bubble oressure. the chanse in hydrostatic ~cessure. grid orifice discharge rate, and gas leakage into the emulsion &se. komputati&s for-the cons&k flow rate case agree well w>th me&u2 gas leak-&e for beds of large particles. For large grid orikes, a simplified model explains the low frequencies observed experimentally for small flow rates.

Gas flow through a fluid&d bed is normally streamline and the pattern of flow depends on the bubbles within the bed and their velocities relative to gas. When the gas velocity for fluidization is low compared with the bubble velocity (as in beds of fine particles) a region of gas circulation or a "c

The successive formation of gas bubbles on the gas distributor of a multi-orifice plate in two-dimensional air-fluidized beds was studied both theoretically and experimentally. A brief theory for the initial bubble formation, which reflects the effects of fluidized particles, was developed based on
