Abstract:By means of computational fluid dynamics (CFD), the solid-liquid two phase flow regularity in WEMCO flotation machine was studied by Euler-Euler model. The influence of turbulence model, solid-phase density and impeller speeds on solid-liquid flow field characteristics, solid homogeneity and power consumption were discussed. Results show that the Shear stress transport (SST) turbulence model can better predict the solid-liquid flow field flow and solid dispersion, and the fluid under the action of the impeller forms a central axisymmetrical structure of the upper and lower circulatory flows. With the increase of impeller speed, the dispersion of solid suspension increases obviously, and the power consumption increases exponentially. With the increase of solid density, the uniformity of solid suspension changes linearly with the rotating speed of the impeller.
