| 摘 要： | 建立了泵站中水泵吸水管和进水池内部三维湍流流场的数学模型，针对泵站中布置了多台机组的多个吸水管和进水池中三维流场的计算边界条件作了深入分析，提出了合理的边界条件。根据分区划分网格的思想，构造了任意形状的水泵吸水管和进水池的贴体计算网格，在任意坐标系中对三维湍流流场的控制方程进行离散，编制了水泵吸水管和进水池内部三维湍流流场数值模拟的计算程序。数值模拟计算了泵站中水泵吸水管和进水池内部三维湍流流场。在数值模拟基础上，可对泵站中水泵吸水管和进水池内部流态进行评估。

| Abstract: | A numerical model for three-dimensional turbulent flow in the water inhaling pipe and the sump of the pumps in the pump station is presented. A reasonable boundary condition for the flow in the water inhaling pipes and the sump of the pumps, each of which may have different flow rate respectively is proposed. The finite volume method is employed to solve the governing equation using the body fitted grid generated by multiblock grid technique. Using the method obtained in this paper, the fluid flow in the water inhaling pipes and the sump of the pumps in the pump station is calculated. The numerical result of the examples is fairly good. |
