| Abstract: | The paper brings up the Combined-sills are made in the forebay to eliminate the circulation and vortex of the diffusing flow. Numerical Simulation of three-dimensional turbulent flow is applied to the complicate flow before and after sills. The results are validated by the hydraulical model test. The computational results are in good agreement with the experimental data. The flow pattern is obviously improved. The Combined-sills has been successfully applied to the pumping project. |
