摘要
应用水平方向上是正交贴体坐标系、垂直方向上是笛卡尔坐标系的混合数值网络系统和三维紊流数值模拟的方法 ,模拟了泵站前池水流流态。计算结果表明 ,对具有复杂几何边界的泵站前池水流 ,特别是前池中设置几何尺寸相对较小的底坎、导致墩等情况 ,方法非常适合。可以较好地模拟出局部区域复杂的水流流态 ,生成网络的计算工作量小 ,能非常方便地进行不同整流方案的计算比较 。
Three dimension turbulent flow in forebay of pumping station is numerically simulated with finite volume method and hybrid grid technique. The hybrid grid system consists of orthogonal body fitted curvilinear coordinate in horizontal dimension and Cartesians coordinate in vertical dimension. Two numerical computation examples were adapted to test the simulating method and simulated results were compared with experimental data. The primary results showed that the hybrid grid method and corresponding mathematical model are especially suitable for simulating complicated flows in forebay of pumping station, in which bottom sill, diversion wall and underwater piers were installed.
