摘　　要：本文利用ｋ－ε－Ａｐ两相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预估转轮叶片面的泥沙磨损。By using the two-phase turbulence model and the k - ε - Ap model, silt-laden flows through a hydraulic turbine runner has been calculated. Based on the calculated liquid and solid phase velocity fields, the silt abrasion prediction on runner blade surfaces has been carried out.
