摘要
采用数值模拟方法对冲击冷却的流动和传热过程进行了三维数值研究。特别研究了在冲击孔叉排方式下,相邻孔间距、冲击距离以及射流入口雷诺数对冲击表面冷却流动传热特性的影响规律。
Three-dimensional numerical study is conducted to investigate the heat transfer characteristics for jet impingement cooling configurations. The effects of the distance of adjacent holes, the impinging distance and jet Reynolds number on flow and heat transfer characteristics at the target wall are investigated extensively under the staggered holes arrangement.
