摘要
水工建筑物进水口前经常会出现漩涡。根据漩涡是否吸气,将其分为吸气漩涡和不吸气漩涡,指出吸气漩涡会造成水工建筑物和水力机械的破坏。分析和总结漩涡产生的影响因素、漩涡危害以及漩涡消除方法等研究成果,回顾了通过物理模型和数值模拟对进水口吸气漩涡进行研究的最新成果。
The vortex often appears at the intake of a hydraulic structure. The vortex is divided into vortex with an air-core and vortex without an air-core, where the former can damage the hydro-engineering and hydro-machine. A brief review of the advances of research on vortexes in intakes is presented in this paper. The influencing factors, damage, and elimination method of vortexes are analyzed. The latest achievements in the research on vortexes at intakes with physical and numerical models are reviewed.
