Estimation of Spatial Distribution of Bubbles in Gas Solid Fluidized Bed

Abstract

A new mathematical model describing the spatial distribution of bubbles in the gas-solid fluidized bed was developed. From a comparison of calculated results with experimental results, this model was found to be useful for predicting the spatial distribution of bubble characteristics, such as bubble size, bubble flow rate and bubble frequency. It was also shown from calculated results of the radial position at which the maximum bubble flow rate appeared in beds that the geometrical similarity rule was not established for the radial distribution of bubbles in a fluidized bed.
