以浙江省诸暨轴流泵站为例,基于三维湍流Navier-Stokes控制方程,采用标准κ-ε模型和SIMPLEC算法对轴流泵站进行了数值模拟,分析了开敞式进水池的水流流态和轴流泵叶轮进口断面的轴向流速分布,进而提出了进水池后壁距尺寸优化、管后隔板和后墙隔板3种技术改造方案,并比较了3种技术改造方案下的模拟结果。结果表明,管后隔板为减少该轴流泵站进水池回流的最佳技术改造方案。 Taking Zhuji Axial Flow Pumping Station in Zhejiang Province for example, based on the three-dimensional turbulent Navier-Stokes control equation, the standard κ-ε model and the SIMPLEC algorithm were used to simulate the axial-flow pumping station. The flow pattern of the open-ended inlet was analyzed And the axial flow velocity distribution of the axial section of the axial flow pump impeller, and then put forward three kinds of technical reformation schemes for the size of the rear wall of the inlet tank, the rear bulkhead and the rear wall bulkhead, and compared the simulation under the three technological reformation schemes result. The results show that the pipe after the diaphragm to reduce the axial flow pump station into the pool of the best technical transformation program.
