摘　　要：为了高精度模拟水流通过水工建筑物时的流场特性,采用CLSVOF法并引入RNGk～ε紊流模型的新型数值模拟方法,对某水电站曲面X型宽尾墩泄流时的水力特性进行了三维数值模拟研究,获得了宽尾墩闸室内水流流态、水面线、流速、压力等水力参数。数值模拟结果与物理模型试验结果吻合良好,验证了CLSVOF数值模拟方法的可靠性。In order to accurately simulate the flow field of hydraulic structures, 3 - D numerical simulation was carried out for flood discharge and energy dissipation process of conical X -shaped flaring gate piers in a hydropower project by using Coupled Level Set and VOF （ CLVOF ） method and RNG k - ε turbulent model. The variation laws of flow pattern, water surface profile,velocities and pressure distributions in lock chamber with conical X - shaped flaring gate piers were obtained. The results of numerical simulation were compared with the model test data and good agreement was found, which verifies the reliability of CLVOF method.
