摘要:
结合泵站锥形侧向前池工程设计，应用大型商业软件建立其三维数学模型，基于CFD数值模拟技术，分析了泵站锥形侧向前池水流流动特性。结果表明，水流经过锥形侧向前池折向弯曲进入进水池，前池流态较为平顺，但进水池水流主流偏向一侧，形成较大回流区，低流速分布范围较广；水流进入1# 至4# 进水池时弯曲程度越大，进水池断面流速分布均匀度越来越小，甚至出现负值，会降低水泵机组工作效率；当泵站设计采用锥形侧向前池时，进水池水流流态需要通过工程措施整流，或创新设计新型进水池。
Abstract:
Combined with the design of the conical forebay with side-intake of pump station，three-dimensional mathematical model with large commercial software is established.Based on the CFD numerical simulation technology，the flow characteristics of the water flow in the conical forebay with s ide-intake of the pump station are analyzed.The results showed that the water flow through forebay with side-intake fold to enter the water inlet by bend，the flow of the conical forebay with side-intake are more smoothly，but the mainstream flow into side of the conical forebay with side-intake，a large recirculation zone is formatted.Low velocity distribution is in wide range.When the bending degree of water flows into the 1# to 4# is bigger and bigger，the distribution of flow velocity in the water inlet section is smaller and smaller，and even negative value will decrease the working efficiency of the pump.When the pump station is designed with the conical forebay with side-intake，the flow pattern of the water inlet needs to be rectified by engineering measures or innovati ve design of the new type of the water inlet.
