沿平板具有微槽结构表面的流动沸腾传热实验研究

RESEARCH ON FLUID FLOW BOILING HEAT TRANSFER ON THE SURFACE WITH MICROCHANNELS

本文报道了甲醇沿刻有矩型微槽表面的平板流动沸腾时传热特性的实验研究所获得的单相对流直到临界沸腾的ｑ″－Ｔω特性曲线，考查分析了流速，过冷度和微槽结构对传热特性、沸腾状态以及临界热负荷的影响，并与光表面情况进行了对比。

Experimenta were conducted to investigate the single-phase forced-flow convection and boiling characteristics of subcooled liquid flowing on the surface etched with dricrochannels of rectangular cross-section. compared with smooth surface, convection flow boiling and critical heat flux were augemented on the surface with microchannels, especially on the surface with more microchannels or higher aspect ratio.
