中文摘要：

本文实验研究了地面重力环境中过冷度和加热铂丝直径对FC-72和丙酮池沸腾传热临界热流现象的影响。实验结果表明,临界热流具有明显的尺度效应,其特征随Bond数范围的不同而不同,但具体的分区准则依赖于工质的物性。在中等和大的Bond数区域,过冷度对临界热流的影响与铂丝直径无关;而在小Bond数区域,过冷度效应与尺度明显相关。

英文摘要：

The influence of subcooling and heating platinum wire diameter on the phenomenon of pool boiling heat transfer of FC-72 and Acetone in normal gravity environment has been studied in the present paper.The experimental results indicate that there are some obvious scaling effects on CHF and the character is different with the change of the range of Bond number,and the actual subarea relies on the material properties.For normal and large Bond numbers,the influence of subcooling on CHF is independent of the platinum wire diameter,however,for the small Bond number,the subcooling effect significantly correlates with the wire scaling.
