摘要
以鞍子河水库溢洪道为研究对象,采用FLUENT软件、利用 k~ε湍流模型和VOF法处理自由水面,对迷宫堰过流能力进行数值模拟。数值模拟结果与试验结果对比表明,采用的模型能够较精确的模拟迷宫堰的过流能力。计算发现,迷宫堰在堰上水头较高的情况下,对计算模型的边界条件进行优化后,可以减小计算误差,为迷宫堰的工程设计提供参考依据。
Combined with the FLUENT software , k- εturbulent model and VOF method ,the free water surface is han-dled to simulate the flow capacity of the labyrinth weir on the spillway of Anzihe Reservoir .The comparison between the numerical simulation value and test value shows that using this model can accurately simulate the flow capacity of the labyrinth weir .Simultaneously ,it is found through the calculation that under high weir head and after optimizing the cal-culation model ,the calculation error can be decreased ,which could provide a reliable basis for the engineering design of labyrinth weirs .
