| Abstract: | In this paper,the RNG two-equation turbulence model was used to simulate the three-dimensional turbulence flow.The volume of fluid method(VOF) was introduced into the iteration of calculation,to solve the curved free water surface.The adaptive Cartesian grid and the fractional area volume obstacle representation method(FAVOR) was used to handle the complex boundary condition and the turbulence flow field of main spillway in the Dahuofang reservoir was simulated successfully.The curvilinear free surface,the magnitude and distribution of the velocity,the pressures on the spillway surface,three-dimensional flow field distributions were obtained.The calculated result was in good agreement with the experimental data. |
