摘要
针对泵站双进水口进水池内三维湍流流场,给出了合理的边界条件,建立了泵站双进水口进水池内三维湍流场的数学模型。采用分块网格方法,构造了泵站双进水口进水池的贴体计算网格。采用有限体积法离散三维湍流控制方程,对双进水口进水池内三维湍流场进行了数值模拟。
A. numerical model for 3-D turbulent flow in the sump of the pump station is presented. A reasonable boundary condition for the flow in the sump with double water intakes, each of which may has 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 sump of the pump stations with two water intakes is calculated. The numerical result of the examples is fairly good.
