Abstract：The full factor experimental design and Euler-Euler multiphase flow model were used to simulate the solid-liquid twophase flow in the whole flow field of alkaline circulating pump. The external characteristics of alkaline with different particle diameters (0.2, 0.6, 1.0 mm), different particle volume fractions (5%, 15%, 25%) and different particle densities (2 400, 2 800, 3 200 kg/m3) were quantitatively analyzed. The results show that the particle volume fraction and the interaction between particle volume fraction and particle density have a significant influence on the external characteristics of alkaline circulation pump. The effect of particle diameter and particle density on the flow field,which are related to particle mass. In addition, the mathematical model of different particle properties and the characteristics of the alkaline pump were established. Quantitatinve numerical prediction of external characteristics of the alkakine circulation pump′s transport medium containing solid particles, which provides theoretical reference for the hydraulic design of the alkaline pump.
