| Abstract: | In order to study the flow characteristics of sand-water inside the turbine of Yingxiuwan Hydropower Station,the sand-water flow in the turbine is numerically simulated,and the flow of sand-water in the runner of turbine is analyzed.The results show that the sediment is mainly distributed at the inlet and outlet edges of inner blades near the runner band,which have guiding significance for the study of sediment erosion of turbine. |
