摘　　要：目前国内深潜池建设工程少、运维时间短,相关研究还处于探索阶段,缺乏相应的标准指导工程建设。而深潜池的规模一般较大,很难通过实验获得水流速度和方向等参数。为了给深潜池池水循环系统设计的校核、优化提供技术指导,以建筑内深潜池的流体域为研究对象,通过计算流体力学(CFD)模拟技术探索了不同工况时深潜池给水口的适合参数、布置方式以及运行过程的流速、流线分布情况。结果表明,送水口采用小孔径、螺旋状,且底部为主、侧流为辅的布置方式,可以达到较好的水流均匀性和循环效果,有效降低了对人员的潜在危险。In China,there are hitherto a limited number of construction projects for deep diving pools,and the operation and maintenance period is relatively short.Relevant research is still at the exploratory stage,and there is a dearth of corresponding standards to guide the construction of such projects.Nevertheless,the scale of deep diving pools is typically large,and it is challenging to obtain parameters like water velocity and direction through experiments.To offer technical guidance for the verification and optimization of the design of the deep diving pool water circulation system,the fluid domain of the deep diving pool within the building was selected as the research object,and the appropriate parameters,layout mode,flow rate,and streamline distribution of the deep diving pool water supply port under different working conditions were investigated through CFD simulation technology.The water supply outlet adopted the configuration of small apertures and a spiral form,with the bottom flow being dominant and the side flow being supplementary.This could achieve better uniformity of water flow and circulation performance,and effectively reduce the potential hazard to personnel.
