摘　　要：射流冲击换热是一种有效的强化换热方法,射流喷嘴的个数及间距直接影响其换热效果.采用数值模拟方法对高温高速气体射流冲击倾斜平板的换热特性进行研究,主要研究了单喷嘴和双喷嘴及喷嘴间距对其换热特性的影响.研究结果可为高温高速气体射流冲击的工程应用提供参考.Jet impinging is an available method for strengthen heat transfer.The unit and space of the nozzle influences directly the heat transfer characteristics.This paper studies the heat transfer characteristics of the high velocity and temperature jet impinging on oblique plane with the numerical simulation methods,especially the effects of the single and double nozzle as well as the nozzle space.The study results has offered the significant reference for the heat transfer characteristics of the high temperature and velocity jet impinging in the application of engineering.
