摘要
通过采用标准k-ε模型模拟湍流，对小洼槽大型倒虹吸管身段在不同流量下进行三维流场数值模拟，并将Q=12．00m3／s和q=14．00m％两种情况的倒虹吸管身段压强值与原型观测数据进行对比分析．结果表明数值模拟和模型试验资料基本吻合，为小洼槽倒虹吸运行管理提供理论依据。
Using the standard k-ε turbulence model simulate the Xiaowacao inverted siphon flows in different three-di- mensional numerical simulation of flow field. The Q=12.0Om3/s and Q=14.00m3/s in both cases the measured data and nu- merical calculation pressure contrast on tube figure of inverted siphon for comparison, the results show that the numerical simulation results and measured data are basically consistent, providing the reliable basis for Xiaowaeao inverted siphon optimization design.
