Volumetric flow can change due to such factors as variation in the number of moles due to reaction, feed distribution, change of phase, membranes and changes in temperature and pressure. This change in volumetric flow was investigated by varying the fluidized-bed pressure in a two-dimensional steel column. Pressure was impulsively adjusted, showing large transient voids during the transitions after rapid growth of the existing bubbles. The effects of sudden depressurization as well as elevated pressure fluidization were also investigated.
