窄缝通道中液氮的沸腾传热研究:第二部分:窄缝通道尺寸对液氮临界热流密度(CHF)的影响

Boiling Heat Transfer of liquid Nitrogen in the Narrow Channels: Part 2: The Effect of the Geometrical Configuration of the Narrow Channels on the Critical Heat Flux (CHF)

在实验的基础上对窄缝通道中液氮的临界热流密度进行了实验研究。实验针对3个不同长度和间距尺寸的窄缝通道在多方位倾角的情况下进行。系统研究了窄缝的方位倾角和窄缝的几何尺寸对临界热流密度的影响,同时对液氮的膜态沸腾进行了研究。

The critical heat flux of liquid nitrogen in the narrow channels is experimentally investigated. The experiments are conducted in three different narrow channels. The influential effect of the geometrical configuration on the critical heat flux is systematically studied, and at the same time, the film boiling in the narrow channels is also studied.
