水轮机导叶双列叶栅的水力优化

Hydraulic optimizahon of double cascades of hydraulic turbines

以水力损失为目标函数，对固定导叶、活动导叶叶型及周向相对位置进行了优化．计算结果表明：与常规方法相比，本文方法用十水轮机导叶双列叶栅的水力设计能提高其水力效率．

By taking the minimum hydraulic losses of double cascades as the objectivefunction, the profile of stationary vanes and guide vanes and their relativecircumferential positions are optimized. The optimization results show that the design method can raise the hydraulic efficiency of the diversion components compared with the traditional design methods.
