| 摘 要： | 应用正交曲线坐标系下的二维水深平均数学模型对泵站的前池流态进行了数值模拟。采用Poisson变换生成正交网格，SIMPLEC方法求解离散方程。根据模拟出的流速场图和断面平均流速分析了泵站正向进水前池扩散角以及开机决策对前池流态的影响，结论与由试验经验所得的泵站设计理论完全一致。

| Abstract: | The 2-D average water depth mathematical model in orthogonal curve-linear coordinate systemis used for the numerical simulation of the flow pattern in the front inflow forebay of pumping station. Theorthogonal gird is generated by Poisson equation, the pool bottom elevation data of the gird points is given byquadrilateral interpolation method, and the equations is solved by SIMPLEC method. The influence of thechange of divergent angle and the selection of running pumps on the flow pattern in the forbay is analyzed bythe simulated velocity field and the average vertical velocity, the conclusion is selfsame with the designtheory of forbay which based on experiments. |
