Numeration Simulation of Solid-Liquid Two-Phase Flow in Centrifugal Sewerage Pump

Abstract:

By Means of Fluent 6.3，the paper simulated the solid-liquid two-phase flow to a centrifugal sewerage pump，using Eulerian Mixture Model under different working condition and different particle size. The simulation draws some conclusion on distributive rules of solid particle inside impeller passage. The results for this simulation were as following: Distributive rules of solid particle inside impeller passage mainly relate to particle size. Meanwhile，the volume fraction of particles and operation condition have influence on distributive rules of solid particle. The simulated results can explain commendably that attrition took place inside pump passage when pump transported solid-liquid two-phase flow. Meanwhile，the simulated results have reference price to improve the design for pump and performance of pump.
