| 摘 要： | 该文对三峡永久船闸末级闸首阀门段输水廊道进行了数值模拟,对阀门段输水廊道的内部水流流动特征进行了分析,并研究了阀门后廊道顶部的压力特性,分析比较了以不同速率开启阀门及不同开度下紧急关闭对阀门段输水廊道内部流场的影响。将二维结果与三维结果及实验结果进行对比,变化趋势基本一致,验证了边界条件提法的合理性及数值方法的可行性。该研究对永久船闸阀门开启速率及紧急关闭时阀门开度选择具有一定的指导意义。 |

| Abstract: | Numerical simulation of the water-filling tunnel of the Three Gorge Lock's last chamber is presented in this paper.The inner flow characteristics including the pressure in this tunnel are analyzed.The effects of the gate opening speed and opening of the gate for emergent closing on the inner flow are also investigated.It shows that the two dimensional results are in agreement with the results of three dimensional analysis and the experiments.Some useful suggestions are drawn based on this research for the operation of the Three Gorges Lock. |
| Keywords: | Three Gorges Lock hydrodynamic performance numerical simulation |
