摘 要: 在液氮自然循环流动时,对竖直多孔表面管管内沸腾换热及外管单面加热时竖直多孔表面套管内沸腾换热,进行了实验研究,分析并讨论了通道的当量半径、热流密度及含气率对沸腾换热的影响。 The experiments are carried out on the liquid nitrogen boiling heat transfer in the vertical tube and concentric vertical tubes of porous surface. The influences of the equivalent radius of channel, heat flux and ratio of bubble on the boiling heat transfer are analyzed.
