摘要
本文采用数值模拟和试验研究的方法,探讨水轮机转轮叶片间叶道涡产生的机理;通过强度计算,分析叶道涡区域叶片静应力和频率的变化,分析了叶道涡对水轮机运行稳定性的影响。
In this paper, depending on numerical simulation and test, the occurrence of the interblade wortex between the turbine runner blades is discussed. Depending on the mechanism calculation, the shift of blade static-stress and frequency of the interblade wortex cavity are analyzed and then its influence on the turbine safety operation is also analyzed.
