| Abstract: | The flow field in the centrifuge slurry pump is simulated by using Fluent. The solid-liquid two-phase flow inner pump on the condition of different initial concentration and different diameters in the pump are simulated. The concentration distribution of the particles information in the impeller and volute are discovered. The general rule of the distribution of particles in the impeller and volute is analyzed,Based on the calculated results under different operating conditions. |
