涡流式内消能工及其在高水头泄水建筑物中的应用

Application of Turbine Internal Dissipator in High Head Outlet Structures

分析涡流式内消能工的结构和消能机理，对单向涡流式、同轴反向涡流式、竖井涡流式内消能工的水力特性和消能情况进行综述。试验表明，内消能工试验不存在比尺效应。内消能工内水流脉动能量的产生、输移、损耗等问题有待进一步研究。综合各类消能工的优点，将其布置成混和形式，也是涡流式内消能工的研究方向。

In this paper,the structure of vortex flow in inner energy dissipator and its principle of energy dissipation have been analyzed.The hydraulic properties and energy dissipation in inner energy dissipator of one direction vortex flow,coaxial reverse direction vortex flow and vertical shaft vortex flow have been summarized as well.Experiment shows that there exists no scale effect in inner energy dissipator.Some problems concerning the generation producing,transfer and dispersion of water flow pulsating energy in inner energy dissipator need further studies.Further research on vorter flow should be armed at the mixed arrangement of the energy dissipators with the advantages of each kind of inner energy dissipator taken into account.
