摘　　要：采用流体体积函数法(VOF)处理水气交界面,与标准k-ε二方程紊流模型耦合,并采用结构网格与非结构网格结合的方式处理复杂的边界形状,模拟了加有消能栅的消力池前后的水流流态。通过模拟计算,得到不同工况下消力池及无压隧洞内的水流流态等,数值计算结果与模型试验吻合较好。In this paper, the flow flied of stilling basin with hanging grid in a free flow tunnel is simulated, combined with κ-ε turbulence model, the volume of flow（VOF method） is used to deal with the interface between gas and water. The structured and unstructured grid is applied to treat the irregular boundary. The flow pattern of different dissipation condition in tunnel is obtained. The calculated result is in good agreement with experimental data.
