水轮机转轮泥沙磨损的数值模拟

Numerical Simulation on Silt Abrasion in a Hydraulic Turbine Runner

本文利用k－ε－A_p两组湍流模型计算水轮机转轮中泥沙固液两相湍流。根据液相和固相三维流速场的计算结果数值模拟了转轮叶片面的泥沙磨损。

By using the two-fluid model and the k-ε-Ap turbulence model,silt-laden flows through a hydraulic turbine runner has been calculated. Based on the calculated liquid and solid phase velocity fields, the numerical simulation of silt abrasion on runner blade surfaces has been carried out.
