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
## AbstracbIn gas-fluidized beds bubbling starts when the voids formed by the oscillating bottom layer of the bed exceed a minimal size. The so-called vibration criterion derived predicts the porosity at the bubble point in close agreement with the experimental data. Comparison of the other criter
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
