压力洞闸槽进水的数值模拟与分析

Numerical Simulation and Analysis of a Pressure Hole with the Flow of Sluice-gate Well

本文应用K—ε紊流模型数值模拟了压力洞闸槽进水后洞内水流的流动情况。计算中,对K—ε方程及雷诺方程作者采用了皆沿坐标方向分步然后交叉求解的简便数值方法。计算实例所得结果与文献[4]试验资料一致。

In this paper, analysis and calculation of turbulent flow in the pressure hole with the flow of sluice-gate well are presented. A simple and effective numerical model was adopted in the computation. It split the K -ε and Reynolds equations in the x and z directions, then they were alternatively solved. The calculated results show a good agreement with those measured from model test[4].
