摘要
通过对水轮机过流部件内部流动模拟计算,获得了输送含沙两相介质时水轮机过流部件流动不同的规律,分析了水轮机过流部件内部流场的两相流流动机理,并探讨了运行于两相流体(含沙水流)环境下的含沙水流水轮机过流部件的性能及水力损失。
Through the flow simulation calculation of flow passage of Francis turbine, various laws of flow during transport of solid liquid fluid in flow passage of Francis turbine are obtained. The biphasic flow mechanism of internal flow field of flow passage for Francis turbine is analyzed. The performance of silt-laden flow of flow passage and hydraulic loss under condition of biphasic flow（water-sand flow） is discussed.
