Research on Francis Turbine Hydraulic Vibration by CFD

Abstract:

The normal operation of the hydropower station is seriously affected by the vibration problems. This paper is about how to analysis and improve the hydraulic vibration problem by an example of a low head Francis turbine in the southwest of China with higher head. The models was built by using UG and analysed by CFD numerical analysis software to simulate the vibration conditions with air-water two-phase flow. With the reason was found by the the result of numerical calcuate, air compensation method was put out to improve the vibration condition and the optimal volume of the compensative air was calcuated to verify the solution method.
