摘　　要：导流泄洪洞在水利工程中应用十分广泛,本文以辽宁丹东梨树园子水电站为例,针对导流洞改建泄洪洞中的消能问题提出了一种射流-旋流梯级内消能工,并对其可行性和有效性进行数值模拟研究。结果显示,设计的射流-旋流梯级内消能工具有良好的消能效果,建议在工程设计中采用。Diversion and discharge tunnels are widely used in water conservancy projects.Taking Lishuyuanzi Hydropower Station in Dandong,Liaoning Province as an example,this paper presents a kind of jet-swirl cascade internal energy dissipator to solve the energy dissipation problem in the reconstruction of discharge tunnels with diversion tunnels,and carries out numerical simulation research on its feasibility and effectiveness.The results show that the designed jet-swirl cascade internal energy dissipator has good energy dissipation effect and can be used in engineering design.
