Abstract: In any practical slurry pipeline application, the solids that are being transported are invariably multi-sized with sizes varying over three orders of magnitude. The prediction of solid distribution across the pipe cross-section is very complicated due to large number of parameters involved. It can be easily envisaged that not only the solid concentration but also the size distribution of solids vary across the pipe cross-section. This knowledge is important for optimum design of the pipeline. The existing experimental data have been compared with the predictions based on the model proposed by Karabelas. The reasons for discrepancy have been identified and modifications have been proposed. The dimensionless eddy diffusivity is assumed to vary with solid concentration and an optimum relationship has been derived using a semi-emperical approach. The modified model has been found to give more accurate predictions.
