摘要: 以兴隆船闸为例,通过物理模型试验研究,对短廊道输水系统进口漩涡成因进行了探讨,分析了输水阀门运行条件、进口淹没水深、进口形式及固体边界条件对旋涡形态的影响。通过模型试验比较,最终提出了适当增加进口淹没深度同时在进口顶部设置开孔式消涡板等措施,可消除吸气漩涡,为优化设计和运行管理提供了依据,并可为其它类似工程设计提供参考。

Abstract: Physical model tests were performed to discuss the causes of vortices at the intake of short culvert conveyance system of the shiplock at Xinglong hydro-junction. Effects of the operating mode of the water valve, the submerged water depth at the intake, and the intake shape and solid boundary conditions on the vortex pattern were analyzed. By comparing a series of model tests, measures of properly increasing the submerged water depth at the intake while setting vortex plate at the top of the intake were finally proposed to eliminate the air-inhaling vortices. It provided basis for the optimal design and operation management and could be referential for the design of alike projects.

Key words: shiplock, short culvert conveyance system, vortex at the intake, causes of vortex and eliminating measures
