Abstract

Various nozzle geometries for impingement cooling jets have recently been devised and favorable designs for cooling effectiveness have been reported. However, impinging flow and the characteristics of impingement cooling are not sufficiently clear. This paper reports on an investigation of impingement jet cooling techniques. The impingement cooling characteristics by oblique jets through a rectangular nozzle have been clarified. Preliminary numerical simulations have not necessarily presented the details of heat transfer characteristics of the oblique jets.

摘要

最近已经设计出了用于冲击冷却射流的各种喷嘴几何形状，并报道了具有良好冷却效果的设计。然而，冲击流和冲击冷却的特性还不够清楚。本文报道了对冲击射流冷却技术的一项研究。通过矩形喷嘴的斜射流的冲击冷却特性已经得到了阐明。初步的数值模拟不一定能呈现斜射流传热特性的细节。
