A comprehensive computational fluid dynamics (CFD) model was developed in the present study to gain insight into solid-liquid slurry flow in pipelines. The preliminary simulations highlighted the need for correct modeling of the interphase drag force. A two-dimensional model problem was then developed using CFD to understand the influence of the particle drag coefficient on the solids concentration profile. The proposed correlation was then incorporated in a two-fluid model (Euler-Euler) along with the standard turbulence model with mixture properties to simulate the turbulent solidliquid flow in a pipeline. A computational model was mapped on to a commercial CFD solver. The model predictions were compared with the published experimental data of Kaushal et al. and Mukhtar. The predicted results show reasonably good agreement with the experimental data. The computational model and resul discussed in this work would be useful for extending the applications of CFD models for simulating large slurry pipelines.
