摘要:

对某多机组泵站复合前池水流流动进行了CFD 数值模拟计算，结果表明：复合前池各自泵房机组水流流动区域都出现了大范围回流区和低速区，水流流态紊乱，严重影响进水池进水均匀性；各泵房进水池有多台机组处于流速分布低速区和前方进水回旋等不良进水条件，甚至出现大尺度回旋；该多机组泵站复合前池平面布置图不合理，须进行CFD数值模拟或水工模型试验水力优化，获得最优水力性能。

Abstract:

The CFD numerical simulation was carried out on the flow of compound forebay in a multi-unit pumping station.The result showed that there were a wide range of recirculation zone and low speed zone in the flow region of each pump unit,and the water flow regime was disorder, which seriously affected the water inlet uniformity in the intake sump.There were several pump units in bad influent conditions such as low velocity zone and cycled inlet water, even cycled in large scale.The layout plan of the compound forebay of this multi-unit pumping station was unreasonable, which could obtain the optimal hydraulic performance through CFD numerical simulation or hydraulic optimization on hydraulic model test.
