以刘老涧新闸为研究对象,基于Navier-Stokes方程和RNG k-ε湍流模型对多孔闸室及上下游连接段内的三维湍流流动进行了数值模拟分析,对比了不同工况下各典型截面的速度矢量及流线分布,引入漩涡面积比对不同典型截面的流态分布进行了定量分析。结果表明:校核工况下多孔闸门及上下游连接段内水流的整体流速均大于设计工况,最大流速位于校核工况下闸门的底部截面,为9.3 m/s;校核工况下不同截面位置的漩涡面积比均大于设计工况,设计工况下漩涡面积比最大为18.85%,位于顶部截面,校核工况下漩涡面积比最大为21.18%,位于底部截面。

This article takes the Liu Laojian New Gate as the research object, based on the Navier-Stokes equation and RNG k- ε turbulence model, the numerical simulation analysis of three-dimensional turbulent flow in a porous gate chamber and upstream and downstream connecting sections was carried out. The velocity vector and streamline distribution of each typical section were compared under different operating conditions, and the flow pattern distribution of different typical sections was quantitatively analyzed by introducing vortex area ratio. The results show that the overall flow velocity of the porous gate and the upstream and downstream connection sections under the verification condition is greater than the design condition, and the maximum flow velocity is located at the bottom section of the gate under the verification condition, which is 9.3 m/s. The vortex area ratio at different cross-sectional positions under the verification condition is greater than the design condition. The maximum vortex area ratio under the design condition is 18.85%, located at the top section. While the maximum vortex area ratio under the verification condition is 21.18%, located at the bottom section.
