摘　　要：窄缝通道中的液氮沸腾传热特性有别于开放空间中的情况。文中对常压下液氮在矩形窄缝通道内的沸腾传热进行了实验研究 ,系统地研究了窄缝几何结构参数和倾角对液氮的沸腾传热特性的影响。The boiling heat transfer of liquid nitrogen in the narrow channels differs from that in pool boiling. In the present study, the boiling heat transfer of liquid nitrogen in narrow rectangular channels is experimentally investigated under atmospheric pressure. The influential effect of the geometrical configuration of the narrow channels on the boiling heat transfer in liquid nitrogen is studied.
