摘要
结合西龙池抽水蓄能电站中岔管部分的设计要求,对带有月牙肋板的三岔管水流进行数值模拟研究.计算采用SIMPLEC方法进行压力迭代,求解三维k ε紊流方程.较好地复演了三岔管管内水流的流速场,通过和物理模型实验结果验证,肯定了所采用的数值模拟方法的合理性.
In accordance with the design requirement for the bifurcated pipe of Xilongchi Pumped- Storage Hydropower Station, the flow condition in the pipe reinforced by crescent ribbings is studied with Numerical simulation; in which 3-D k-ε turbulent flow equations and SIMPLEC algorithm are used. Based on this, the flow velocity field in the bifurcated pipe is simulated and a satisfactory tesult is obtained. The numerical simulation is verifiedto be reasonable through the physical model test.
