Prediction of concentration and particle size distribution in the flow of multi-sized particulate slurry through rectangular duct

Abstract

The analytical model proposed by Karabelas [AICHe J. 23 (4) (1977) 426] has been modified and upgraded to predict the concentration profile and particle size distribution across the cross-section of rectangular duct for the flow of multi-sized particulate slurry. The predictions have been compared with the experimental data reported by Kaushal [Prediction of particle distribution in the flow of multi-sized particulate slurries through closed ducts and open channels, 1995]. The limitations of the original model have been identified and modifications incorporated to take into account the effect of solid concentration on settling rate and particle diffusivity. The predictions by the modified model are in good agreement with the experimental results. © 2002 Elsevier Science Inc. All rights reserved.
