在两流体模型的基础上。利用ｋ-ε-Ａｐ两相湍流模型计算流过混流式水轮机转轮的三维固液两相湍流。然后根据液相和固相三维流速场的计算结果，采用图尔萨（Ｔｕｌｓａ）大学磨蚀研究中心发展的泥沙磨损模型，预估转轮叶片表面的泥沙磨损情况。
Based on two fluid models. Calculation of Three-Dimensional Solid-Liquid Two-Phase Turbulent Flow in a Francis Turbine Runner Using k-ε-Ap Two-Phase Turbulence Model. Then, based on the calculated results of the liquid and solid three-dimensional velocity fields, the sediment wear model developed by the Tulsa University Abrasion Research Center was used to estimate the sediment wear on the rotor blade surface.
