摘要

对常温、大气压下水在开孔泡沫铜中池沸腾的传热特性进行了试验研究

观察了开孔泡沫铜中汽泡的生长特性及其变化规律

并与水在光管加热面的池沸腾特性进行了对比。试验结果表明:水在泡沫铜中池沸腾时

汽泡脱离直径和汽泡脱离频率随热通量的增加而不断增大

泡沫铜对水的池沸腾传热具有很好的强化效果。根据试验结果

得到了水在开孔泡沫铜中池沸腾传热的传热系数拟合关联式

为进一步的研究提供了依据。

Abstract

The pool boiling heat transfer performance of water in porous copper foam was investigated experimentally at room temperature and atmospheric pressure.The growth characteristics of bubble in copper foam with open cells were obtained by visual observation.The results showed that the bubble escape diameters and bubble escape frequency increased with the increase of heat flux

and the enhancement effect of copper foam for pool boiling was obtained by comparing with plain tube.A correlation for water pool boiling heat transfer coefficient in copper foam was obtained

providing a basis to further study.
