在两流体模型的基础上，利用k--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 the two-fluids model, we use thek--Ap turbulent model to simulate the 3D two phasesflowfield passing through a Francis turbine runner.Andthen, based on the numerical simulation results of liquid andparticulate phase, using the abrasion model developed by theErosion & Corrosion Research Center of TulsaUniversity, we give erosion prediction of the blades.
