| Abstract: | According to the monitoring index of no passing turbine flow for cavitation and destructive condition of water turbine,this paper monitors various physical indexes of flow,cavitation site and modality.Based on the obtained various physical indexes,cavitation principle of water turbine is analyzed.Results show that the measures with site observation and numerical simulation can be used to predict the development tendency of cavitation destruction for water turbine and provide the evidence for real-time maintenance. |
