Effect of Fluid Viscosity and Promoter Parameter on Pressure Drop in a Batch Liquid-solid Fluidized Bed with Go-axial Disc Promoter

Abstract

A correlation has been developed for the prediction of pressure drop in terms of friction factor for a batch liquid-solid fluidized bed with a co-axial disc promoter using fluids of varying viscosity. The experimental data obtained for pressure drop with different fluid mass velocity, initial static bed height and disc spacing of the promoter have been analyzed using dimensional group. In this article, the pressure drop data have been expressed in terms of friction factor to develop the correlation. The predicted values of friction factor using the developed correlation have been compared with the corresponding experimental ones and have been found to agree well.
