结合盘石头水库输水洞模型试验,应用现代紊流理论,对输水洞下游锥形阀消力池内的复杂流动结构进行了观测试验和定性分析,并从紊流力学的角度对耗散作了机理性分析.认为锥形阀消力池内流态的显著特点是锥底存在较大范围的卷吸区,流态具有强三维性,大尺度涡拟序结构对池内的流速分布、压强分布及消能起主导作用,为进一步进行锥形阀消力池内流态及消能的定量计算奠定了基础.

Combined with the model test of Panshi Reservoir water transmission hole, modern turbulence theory is applied to observe and qualitatively analyze the complex flow structure in the conical valve drainage tank downstream of the water conveyance tunnel, and the dissipation is analyzed mechanically from the perspective of turbulence mechanics. It is believed that the significant feature of the flow state in the cone valve damping cell is that there is a large range of winding and suction zone at the bottom of the cone, the flow state has strong three-dimensional nature, and the large-scale vortex sequence structure plays a leading role in the flow velocity distribution, pressure distribution and energy dissipation in the pool, which lays a foundation for the further quantitative calculation of the flow state and energy dissipation in the cone valve damping cell.
