| 摘 要： | 依奇点分布法和前人分析实验得到的含沙水流中固体颗粒的受力分析结果,利用相对阻塞和相对抽吸的观点对含沙水流中水轮机导叶进行设计。经模型试验表明,与传统方法设计的导叶相比,用本文提出的方法设计的导叶在含沙水流中运行时,水力效率高,耐磨蚀。

| Abstract: | Based on the singularity method and predecessors' analysis results of force acting on sandy particles in silt laden water flow and using the view-point of relative jam and suction. the guide vane of hydraulic turbine operated in silt laden water flow is designed. With the help of model tests,it is found that the presented design method of the guide vane can provide a higher hydraulic efficiency and better erosion-proof than conventional method. |
