摘要
实验研究了垂直向上窄缝环形管内流动沸腾换热特性和流型变化 ,窄缝宽度为 1～ 2 .5mm .实验结果表明 ,窄缝内沸腾传热有明显强化 ,并出现了区别于常规尺寸管内的两相流型和局部换热特性 .
Experiments are conducted to investigate the characteristics of boiling heat transfer of F-113 flowing through annular tube with gap of 1, 1.5 and 2.5 mm. The data show that due to the limitation of narrow space the two-phase flow regime changes, and the boiling heat transfer is enhanced obviously.
