【Abstract】 In this paper, the simulation of the three\|dimensional turbulent flows through a hydraulic pump turbine runner at pump modes has been conducted based on κ\|ε turbulence model with body\|fitted coordination and staggering grid system. SIMPLEC algorithm is adopted in the numerical procedure. Velocity distributions and pressure distributions through the impeller are indicated. The results of three\|dimensional turbulent flows are displayed by a commercial software, Tecplot+3D Flow, version 7 0.更多还原
