摘要 为了研究水泵水轮机的水轮机工况大流量区域的流场特性,依据某抽蓄电站水 泵水轮机进行建模,分别采用结构化和非结构化两套网格,基于剪切应力传输模型和 SIMPLEC算法对该区域流场进行了模拟,并与试验结果进行了比较验证,详细分析了大 流量下转轮内部流动特性。结果显示,水泵水轮机进入大流量区后,由于流体相对转轮 速度的不断提升,转轮流道内生成了周期性分布的涡结构并且涡结构不断增大,向流道 出口边延伸,引起能量损失,且导致转轮叶片压力面上流体速度的上升,进而对数值计 算的网格质量提出了较高的要求,揭示了大流量区计算难度高的内在原因。为水轮机工 况大流量区域的数值计算和流场分析提供了理论依据。

Abstract:  To research the character of the high flow area at turbine mode of the pump turbine, a hydraulic model was established based on a pumped storage station. The SST k- model and two kinds of grids were used to simulate the internal flow fields and the results of the two kinds of grids were compared with the test data .The results show that in the high flow area, there are periodical distribution vortexes in the runner’s flow passages with the increase of relative speed between the liquid and runner .The vortexes increase the energy loss and at the same time, the high speed of the liquid makes high quality grids necessary for simulation, and this is the reason why the high flow area is difficult to simulate. These conclusions can provide a theory basis for the analysis and simulation of the high flow area.
