摘　　要：进水池的流态不仅与进水池结构有关,而且与进水条件有关.传统的数值模拟对泵站进水池进口边界条件垂直入流假设并不符合多机组泵站进水池的情况.整体数值模拟方法的计算区域为整体进水设施,避免了对进水池进口流态直接描述的问题,能够更加准确预测进水池内的流态.Flow patterns of intake sump bear on intake sump structure and inlet conditions. However, the numerical simulation of traditional assumption as to upright inlet boundary conditions fails to correspond with the actual case of muhi-unit pumping station. This paper introduces an integrated numerical simulation, the numerical areas of which entail the whole inlet facilities. Such simulation can avoid describing directly inlet flow of intake sumps and can accurately predict the/low patterns in the sump.
