运用CFD软件Flow-3D和RNGκ-ε湍流模型模拟分析了抽水蓄能电站上水库的进/出水口位置及其形状对流态的影响,并模拟分析了某抽水蓄能电站上水库的流态变化,提出了优化建议。结果表明,上水库圆形库面、进/出水口前设置较长引水渠流态较好且利于主流扩散,当进/出水口两侧有一定距离时可减小环流对库岸的冲刷。 The CFD software Flow-3D and RNGκ-ε turbulence model were used to simulate and analyze the influence of inlet / outlet position and its shape on the flow regime in the upper reservoir of a pumped storage power station and the simulation of flow regime change in the upper reservoir of a pumped storage power station , Put forward the optimization proposal. The results show that the long diversion canal set in front of the inlet / outlet of the upper reservoir has a better flow pattern and is conducive to the mainstream diffusion. When there is a certain distance on both sides of the inlet / outlet, the circulation on the reservoir bank can be reduced.
