摘要
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。
Flow-3D software and RNGκ-ε turbulence model are applied to analyze the flow pattern influenced by inlet/ outlet location and the shape of upper reservoir. And then the flow pattern variation in upper reservoir of a pumped stor- age power station is simulated and the optimization suggestion is proposed. The results show that the flow pattern in up- per reservoir is fairly good for the diffusion of the mainstream if the shape of upper reservoir is round and there is long diversion canal in front of the inlet/outlet, and it can reduce erosion of circulation current to reservoir bank if there is certain distance on both sides of the inlet/outlet.
