摘要
水轮机的稳定性是评价水轮机性能的三项重要指标之一 ,到目前为止稳定性的研究还驻足在试验阶段 ,本文通过建立起尾水管压力脉动分频幅值与转轮出口环量之间的某种联系 ,对利用水力计算来预测水轮机的压力脉动进行了初步的探索。
Stability of the hydraulic turbine is one of the most important indexes for evaluation of hydraulic turbine performance.However,stady on hte hydraulic turbine stability still remains so far at the test stands.This paper suggests an approach,that the pressure pulsation component amplitude of the draft tube have a relationship with the annular liquid flow at the runner exit,and then the hydraulic turbine pressure pulsation can be predicted through CFD.
