摘要
就微三角形槽道内CFC12的流动沸腾换热做了详细的实验研究。研究表明,在微槽道中流体流动沸腾换热比常规尺寸的换热更为强烈,且流动用力相对要小,实验观察发现,在微三角形槽内流体流动沸腾时明显有大量气泡生成,这与其它相关实验得出的不产生气泡的结论是不同的。
The friction factors and heat transfer characteristics of the flow of CFC-12 in micro triangular channels are studied. The experimental results show that the heat transfer in micro-channels is greater than that in normal scale channels, and the friction factors are smaller than that in normal channels. Most importantly,lots of bubbles are seen while CFC-12 boiling in the micro channels upon our experiments,which is different from the result got by others so far. It is explaied in this paper.
