Erosion Prediction of Flow Behavior of Coal Water and Copper Ore Water Slurries

Abstract

Many researchers are working in the field of slurry flow regarding the rheological parameters of multi size particulate flow. It is imperative part of pipeline industry, moreover, one can say that pipeline industry have some reliance on multi size particulate flow. Analyzers have carried out modeling of the erosion of pipes and bends. Computational fluid dynamics (CFD) has been used extensively for particulate slurry erosion divination in pipes and bends, since early 90s with emphasis on various analytical and empirical models. The review of literature in this field has been carried out to understand the extent of work that has been reached and the scope available to work in this field. The present paper, introduces a simplified 3-D algebraic slip mixture (ASM) model along with RNG k-ε turbulent model to obtain the numerical solution in coal-water and copper ore-water slurry flow. The pressure drop, viscosity, density, volume fraction, Reynolds number and Euler number have been compared with the experimental work available in the literature. The solutions have been found to be in good agreement with the experimental data.
