Hydraulic Vibration and Possible Exciting Sources Analysis in a Hydropower System

Hydraulic Vibration and Possible Exciting Sources Analysis in a Hydropower System

To understand the hydraulic vibration characteristics in a traditional hydropower system and identify possible exciting sources that may induce serious hydraulic vibrations in the flow passage, experimental tests and numerical calculations were conducted for different operating conditions. The exper...
