摘要
从水力设计的角度出发,结合CFD技术的具体应用,分析讨论了混流式水轮机转轮压力脉动与转轮出口环量、尾水管中的流速分布、转轮泄水锥及导叶等之间的关系,提出了减轻压力脉动的具体措施,并对利用水力设计来预测转轮压力脉动进行了一些探索。
Viewed from the hydraulic design of runner and combined with actual application of CFD technology, this paper analyzes and discusses some relationship among pressure pulse, annular liquid flow at the runner exit, the distribution of velocity in draft tube, runner cone and wicket gate etc. Then it puts forward some methods of improving pressure pulse.
