Abstract:To study the solid-liquid two-phase flow mechanism in centrifugal pump with different impeller outlet angles,three-dimensional simulation was performed for the solid-liquid two-phase turbulent flow in this kind pump by using Fluent software with Eulerian model,SIMPLEC algorithm and standard k-ε turbulence model.The effects of impeller outlet angle on the solid-liquid two phase flow in the centrifugal pump were fully analyzed.The result shows that the direction of relative motion of particles is towards the pressure side of the impeller,the velocity difference between two phases is more obvious in the impeller with large outlet angle.And more particles accumulate near the pressure side of the impeller with large outlet angle,which results in large particles impact on the tail of the blade.The outlet pressure is increased as the outlet angle becomes larger.
