摘要
采用修正的Ｋ～ε模型封闭Ｒｅｙｎｏｌｄｓ方程作为紊流控制方程，引入通度概念处理不规则边界，引用ＶＯＦ法追踪自由表面，对溢流坝坝面水流进行数值模拟。模型试验验证结果表明，采用本文建立的数学模型对溢流坝水流进行数值模拟是可行的。
n the paper,the closed Reynolds equation based on the revised K～E model is used as the turbulence control equation,the universal concpt is introduced to geal with irregular boundaries and VOF method is introduced to follow up the free surface for the numerically simulating the water flow over the nip bucket. The results suggest that it is feasible to carry out maths modelling of the overflow dam flow with the maths model established in this paper.
