  • The thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed channel are measured by using infrared camera and then the impingement cooling heat transfer coefficients are deduced . the effects of flow and geometry parameters on convective heat coefficients are obtained . the results show that : for a single row normal impingement , the impingement cooling effectiveness is enhanced with the increase of impinging reynolds number or the decrease of hole space to diameter ratio , and the best effectiveness is achieved under the jet - to - surface spacing equals to 2 ; when the jet is oblique to the confined wall , the cooling effectiveness is weaken especially under the jet - to - surface spacing ratio is greater than 2 ; for double rows normal impingement cooling , the cooling effectiveness of rear row jet is weaker than the front row under lower impinging reynolds number or bigger jet - to - surface spacing
    对于单排垂直射流,冲击冷却效果随射流雷诺数的增加、孔间距与直径比的减小而得到提高,冲击间距比为2时换热效果最好;冲击孔中心线向通道封闭一侧倾斜后,射流冲击冷却的范围变窄,当冲击间距比大于2时驻点区的对流换热能力明显降低;对于双排冲击射流,孔排间距与直径比的增加使冲击冷却范围变大,但在两排孔之间区域的对流换热系数有所下降;在较小的冲击射流雷诺数和较大的冲击间距比下,后排射流的冲击换热效果要逊于前排射流。
