abstract

Based on FLUENT software, the standard k–ε turbulence model is adopted to simulate 3D-flow field in the forebay of a combined sluice-pump station. Flow field of the diffusion channel and suction passage is obtained after numerical simulation. Results show that flow in the fore-bay appears side-direction and vortexes exist in it and inlet of the suction passage. According to the results, optimum measures such as changing the wing wall form, extending the sluice pier, adding tri-prisms are conducted on the basis of original design. The vortexes are eliminated finally. Flow in diffusion channel appears front inflow and is improved effectively.
