Abstract：In the hydraulic parameter design of sluice,flow design is very important.Reasonable control of sluice opening can not only make the downstream flow of sluice evenly distributed,but also prevent soil and water loss on both banks and riverbed.In order to analyze the influence of different gate openings on the flow characteristics,the Fluent numerical simulation method is introduced.Considering energy dissipation and flow resistance,the effects of RNG k-ε,RNG k-ω and RSM turbulence model on fluid velocity distribution and energy coefficient are compared and verified under different gate openings through laboratory sluice tests.The research results can provide reference for relevant projects.
