| 摘 要： | 结合西龙池抽水蓄能电站，对有加强肋板结构的三岔管内水流进行数值模拟及物理试验研究，采用SIMPERC方法求解三维紊流方程，选取不同的肋宽比进行数值模拟，得到分岔管水头损失系数随肋宽比变化的规律，较好地复演了三岔管管内水流的运动，能满足工程实际需要，并通过物理模型验证了所用数值方法的合理性和计算精度。

| Abstract: | According to the design needs of branch pipes of Xilongchi Pumped-storage Power Plant, the Numerical simulation of the flow of three branch pipe with crescent costal board and laboratory tests were done. 3D turbulent flow equations and SIMPERC algorithm were used. Meanwhile we choice different costal board width ratios, in order to get the trend of head loss coefficient, the simulating results of the flow in three branch pipe elucidate that the method can meet the needs of the practical projects. Comparisons with laboratory test results, the model captures most experimental trend with reasonable accuracy. |
