Abstract

In order to do the research on the effect of solid particle diameter on the performance of solid-liquid centrifugal pump, based on MRF method and by using Eulerian model, standard k-e model combined with the algorithm—Phase Coupled SIMPLE— carries out constant numerical simulation of internal two-phase flow of the solid-liquid centrifugal pump, mainly analyzes external characteristic and volume fraction and velocity distribution of sand particles on the impeller surface. The result suggests that with the increase in the solid particles’ diameter, the head and efficiency of the solid-liquid two-phase flow centrifugal pump both gradually decrease. No matter how much diameter it is, volume fraction and velocity of sand particles reach the maximum on the surface of blade, and it indicates that abrasion mainly happens on the blade surface of the solid-liquid centrifugal pump. Centrifugal pump can perform better when the solid particle diameter is 0.003 mm or 0.0035 mm because the head and efficiency of solid-liquid centrifugal pump are higher, and centrifugal pump is less affected by abrasion.
