Abstract：Based on the N-S equations the water and sand-water two-phase inner flow fields of the metal volute were simulated,In the entity model and computing area of the volute the SIMPLE algorithm and three-dimensional mixed element type unstructured grids in the Cartesian space were adopted.When transporting the rinsing the standard k-ε model was used;when transporting the solid-liquid fluid with particles,the k-ε-Ap model was used.The movement characteristics of sand-water two-phase flow in diversion components were found out.The inner flow mechanism was predicted and analyzed.The results of simulation were coincident with the material offered by Hydropower Station,which indicated the feasibility of the performance prediction and the optimized design by CFD simulation.water turbine;volute;solid-liquid two-phase flow;CFD numerical simulation
