摘要
在水闸的水力参数设计中,流量设计十分重要.合理控制水闸开度不仅可以使水闸下游流量均匀分布,还可以防止河道两岸和河床的水土流失.为分析不同水闸开度对水流特性的影响,采用Fluent数值模拟方法,引入能量耗散和流动阻力,分析对比了不同闸门开度下RNG k-ε、RNG k-ω和RSM湍流模型对流体速度分布和能量系数的影响,并通过室内水闸试验进行验证对比,研究结果可为相关工程提供参考.
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.
