| 摘 要： | 泵站前池扩散角过大会在池中形成边侧回流，恶化水泵的进水条件，因此一般需要研究适当的整流措施。应用正交曲线坐标系下的二维水深平均数学模型，对大扩散角的正向泵站前池中设置隔墩前后的流态进行了数值模拟，以分析设置隔墩的整流效果。计算中在交错网格上对控制体积分得到离散方程，并用SIMPLEC算法求解。数值模拟表明，对所研究的泵站前池，适当设置隔墩对前池扩散角过大引起的不良流态有明显的改善效果。

| Abstract: | The measures of improving flow conditions should be adopt in the over large divergent angle of fore-bay of a pumping station to avoid the side return flow which would worsen the intake conditions of pumps.In the paper,the improvement of flow conditions in the front inflow of fore-bay of the pumping station with setting separation piers is researched by numerical simulation.The 2-D average water depth mathematical model in orthogonal curve-linear coordinate system is used for the numerical simulation.The dis... |
