采用先进的数值计算技术求解完整的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，辅以双方程紊流ｋ－ε模型，并计入流线弯曲的影响，模拟泄水建筑物曲面边壁紊流的水力特性。实例计算结果与物理模型实测资料符合较好，证明该数学模型可用于预测泄水建筑物曲面边壁紊流的水力特性。
The complete Navier-Stokes equations are solved by advanced numerical calculation, and the two-equation turbulent k-ε model is used. The influence of streamline bending is taken into account to simulate the hydraulic characteristics of the turbulent flow around the curved surface of the spillway. The calculated results of the example are in good agreement with the measured data of the physical model, which proves that the mathematical model can be used to predict the hydraulic characteristics of the turbulent flow on the curved surface of the drainage structure.
