Fenghuangjing new station belongs to the front inflow pump station with large diffusion angle. Large scale off-wall reflux is easy to occur at the bank walls on both sides of the forebay, which can not provide good inlet conditions and endanger the safe and stable operation of the pump station. Forebay at river diversion side of Fenghuangjing new station was taken as the research object. Based on the CFD numerical simulation software, the improvement effect of trapezoidal sill position and height on the flow pattern in the forebay of the front inflow pump station with large diffusion angle was studied. And the numerical simulation results were verified by physical model tests. The results show that when the trapezoidal sill is located at 10 m from the entrance of the forebay and the height of the sill is 1.2 m, the inflow conditions of Fenghuangjing new station can be better improved. The research results can provide technical support and reference for this project and the similar projects.

凤凰颈新站属于正向进水大扩散角泵站,前池两侧岸墙处易发生大尺度脱壁回流,不能提供较好的进水条件,危害泵站安全稳定运行。因此,以凤凰颈新站引江侧前池为例,基于CFD数值软件,模拟研究了梯形底坎位置及高度对正向进水大扩散角泵站前池流态的改善效果,并借助物理模型试验对数值模拟结果进行了验证分析。结果表明,当梯形底坎位于前池入口10 m处且坎高为1.2 m时,可较好地改善凤凰颈新站的进水条件。研究成果可为本工程及类似工程提供技术支持和参考。

凤凰颈新站属于正向进水大扩散角泵站,前池两侧岸墙处易发生大尺度脱壁回流,不能提供较好的进水条件,危害泵站安全稳定运行。因此,以凤凰颈新站引江侧前池为例,基于CFD数值软件,模拟研究了梯形底坎位置及高度对正向进水大扩散角泵站前池流态的改善效果,并借助物理模型试验对数值模拟结果进行了验证分析。结果表明,当梯形底坎位于前池入口10 m处且坎高为1.2 m时,可较好地改善凤凰颈新站的进水条件。研究成果可为本工程及类似工程提供技术支持和参考。

Fenghuangjing new station belongs to the front inflow pump station with large diffusion angle. Large scale off-wall reflux is easy to occur at the bank walls on both sides of the forebay, which can not provide good inlet conditions and endanger the safe and stable operation of the pump station. Forebay at river diversion side of Fenghuangjing new station was taken as the research object. Based on the CFD numerical simulation software, the improvement effect of trapezoidal sill position and height on the flow pattern in the forebay of the front inflow pump station with large diffusion angle was studied. And the numerical simulation results were verified by physical model tests. The results show that when the trapezoidal sill is located at 10 m from the entrance of the forebay and the height of the sill is 1.2 m, the inflow conditions of Fenghuangjing new station can be better improved. The research results can provide technical support and reference for this project and the similar projects.
