摘要
从理论上分析了影响沸腾传热特性的各种因素,以间隙为 1 mm～2 mm的环形狭缝通道中流动沸腾传热的实验数据为基础,给出了三种计算环形狭缝中流动沸腾传热的准则关系式。分别将计算结果与实验数据进行了比较,找出了影响狭缝中沸腾传热的关键因素,确定了可以用来预测该实验范围内的流动沸腾传热的准则关系式。
Factors concerning the characteristics of boiling heat transfer are analyzed theoreti-
cally.Based on the experimental data of boiling heat transfer through annular channels with the gaps
of 1mm～2mm,three correlations which will be used to calculate the heat transfer in the similar con-
ditions are given here.The results obtained from these correlations are compared with experimeotal
data,respectively.The main factors having influence on boiling heat transfer through narrow chan-
nels,and the desirable correlation are figured out.This correlation can be used to predict the flow
boiling heat transfer within the range of said experiment.
