Numerical Simulation of Hydraulic Turbine Based on Fluid-Structure Coupling

摘要：

By adopting the arbitrary Lagrange-Euler (ALE) method of software ADINA, fluid-structure coupling (FSC)calculation of a Francis turbine is conducted. The vibration frequency and mode of the runner in the air and water are obtained. The calculation results show that runner frequency of the turbine is reduced in certain degree under the effect of water pressure and viscous force, and the mode is changed, too. By using dynamic fracture mechanics, the possible cracking damage of the runner is predicated.
