Generalized Model for Bubble Size and Frequency in Gas-Fluidized Beds

Abstract

A generalized bubble-growth model on mean bubble size and frequency has been proposed in bubbling gas-fluidized beds. Correlations on volumetric bubble flow rate, splitting frequency of a bubble, and equilibrium bubble diameter have been considered in this model. The equilibrium bubble diameter was shown to increase linearly with the ratio of volumetric bubble flux to the splitting frequency of a bubble. The proposed model was in good agreement with the extensive data reported on mean bubble size and frequency.
