摘要：By Means of Fluent 6.3, the paper simulated the solid-liquid two-phase flow to a type of centrifugal sewerage pump under different sand size and contain arenaceous concentration conditions, using Eulerian Mixture Model, adopting SIMPLE algorithm, k-epsilon-Ap turbulence model and partitioning non-structure hex grid in the area of flow passage in the pump. The paper analyzed wear characteristics in different parts of centrifugal sewage pump impeller and put forward some means to decrease attrition for impeller. The results can be as theoretical reference for the optimization design of the centrifugal sewage pumps
