| 摘 要： | 通过采用标准k~ε模型模拟湍流，利用VOF法追踪自由水面，对新疆北部小洼槽倒虹吸在不同流量下进行三维流场数值模拟，并将Q=14.00m3/s和Q=16.35 m3/s两种情况的倒虹吸进出口水面高程与原型观测数据进行对比，结果表明数值模拟结果和实测资料基本吻合。倒虹吸进口处有立轴漩涡，为了避免出现这种情况，应尽量在高水位情况下运行，可以减小进口处的水流流速，降低水流的紊动动能。

| Abstract: | By using the standard k ~ ε turbulence model simulation and VOF method to track the free surface of the northern Xinjiang small hollow groove under the inverted siphon flows in different three-dimensional numerical simulation of flow field. The Q = 14.00m3 / s and Q = 16.35 m3 / s in both cases the surface elevation and the import and export siphon prototype observation data for comparison, the results show that the numerical simulation results and measured data are basically consistent. Inverted siphon inlet vertical vortex, in order to avoid this situation, you should be run in the case of high water ,you can reduce the inlet flow velocity and water turbulence kinetic energy. |
