| 摘 要： | 为改善堤、坝等阻碍鱼类洄游的现状应用了鱼道、鱼闸等过鱼设施，采用RNG κ-ε湍流模型和有限差分法对兴隆水利枢纽工程鱼道进行了数值模拟，分析了淹没孔口式横隔板鱼道的流态和紊动能，研究了过鱼池和休息池的水力特性。结果表明，淹没孔口式横隔板鱼道的孔口水流具有固定特性，紊动能的分布空间较广，消能效果较好。过鱼池和休息池内水流的流态较稳定，能满足过鱼对象的需求。

| Abstract: | In order to help fish migrate over the dike and dam,many facilities are adopted,such as fishway and fish lock.In this study,rearrangement group κ-ε turbulence model(RNG κ-ε turbulence model) and finite difference method are used to simulate the fishway of Xinglong hydro-junction project.And the flow pattern and turbulent kinetic energy of the submerged orifice transverse diaphragm plate fishway are analyzed.Then the hydrodynamic characteristics of fish pools and rest pools are studied.The results show that the submerged orifice transverse diaphragm plate fishway has certain hydrodynamic characteristics;the effect of energy dissipation is good with broad space of distribution of turbulence kinetic energy;the flow patterns in fish pools and rest pools are relatively steady and it can meet fishes’ hydrodynamic requirements to pass through the dam. |
