基于数值模拟的某阶梯溢洪道方案优化研究

基于数值模拟方法,利用FLUENT软件对某阶梯溢洪道原设计方案下的泄流能力、闸门全开时的水面线、沿程各段压力等值线、闸门全开时沿程流速分布等流场要素进行模拟计算,根据计算结果分析原设计方案中存在的不足和问题,并提出了新的优化设计方案。研究结果表明:新方案能较好的满足工程设计实际要求,并可对同类型阶梯溢洪道的优化设计提供有价值的参考。

Study on optimization of stepped spillway scheme basedon numerical simulation

Based the method of numerical simulation, this paper simulated and calculated the discharge capacity of original design scheme of stepped spillway, the line of water surface and the equal value line of pressure when sluice gate was fully opened, as well as the velocity distribution along the element process field by use of FLUENT software. According to the simulation result, it analyzed the deficiencies and problems existing in the original design scheme, and put forward a new scheme of optimization design. The simulation results have indicated that the new scheme can meet the practical requirement of engineering design, and can provide a valuable reference for optimization design of the same type of stepped spillway.
