采用标准κ-ε模型和SIMPLE算法,对泵站侧向进水前池水流流态进行了数值模拟。根据模拟出的前池水流的速度矢量图、断面垂线速度分布图及泥沙体积浓度轮廓图分析了泵站侧向前池进水角α和开机决策及介质分别为清水和浑水对泵站进水流态的影响,所得结论与泵站前池的设计理论十分吻合,这对泵站的设计和改造都具有指导意义。
The standard κ-ε model and SIMPLE algorithm are used to simulate the water flow in the forebay of the pump station. According to the simulation of the velocity vector of the forebay flow, vertical velocity profile and sediment volume concentration profile of the pump side of the pool into the water angle α and boot decision-making and media were water and muddy water on the pump Station influent flow conditions, the conclusions drawn with the front of the pumping station design theory is very consistent, which is of guiding significance for the design and retrofit of the pumping station.
