减小压力脉动，避免空化及减少泥沙磨损是设计中水头混流式水轮机的主要课题。要设计一种理想的转轮，其运行范围应比正常设计水头变化宽得多并且需要的维护应最小。简述了应用水力流志设计参数、ＣＦＤ辅助分析及模型试验的方法，力求达到上述目的。 Reducing pressure pulsations, avoiding cavitation, and reducing sediment wear are the major topics in the design of Francis turbine. To design an ideal runner, the operating range should be much wider than the normal design head variation and the maintenance required should be minimal. The methods of applying hydro-logging design parameters, CFD-aided analysis and model tests are briefly described in an effort to achieve the above objectives.
