摘要
Abstract
By introducing the air-water two-phase flow model, the k-ε turbulence model was employed to simulate the complicated turbulent flow fields on the surface of overflow dam with frusta of Yinpan Hydropower Station. The unstructured grids were used to treat the irregular boundaries, and the finite volume of fluid method was applied to the iteration of calculation. The curvilinear free surface, velocity and pressure distributions were obtained by means of 2D and 3D numerical simulations. The results of 2D and 3D numerical simulations were compared with the test data. A conclusion is drawn that compared with those of 2D numerical simulations, the results of 3D numerical simulations fit physical model test ones better. Especially for the pressure on the inlet and the occurrence positions of hydraulic jump, 3D numerical simulations are more accurate.关键词
