Numerical Simulation of 3D Cavitation Turbulent Flow in Francis Hydro-turbine Passage on Mixture Modeling Technology
摘要
Abstract
The numerical simulation of three dimensional cavitation turbulent flow in Francis hydro-turbine passage was conducted based on the mixture model for homogeneous multiphase flow hypothesis in the Euler–Euler approach and the Schnerr and Sauer cavitation models.The standard k-? model,SIMPLEC algorithm and multiple reference frame model were used.The distributions of the water-vapor volume fraction in blade passage and draft tube were obtained in special case by the software ANSYS FLUENT.The position and degree of cavition in turbine passage were analyzed.The results show that the method can be used to simulate the 3D cavitation turbulent flow and true multiphase flow with cavitation in Francis turbine than one-phase model.关键词
