摘要: 本文报道了机械加工表面多孔管(JK-1管)水平管外降膜沸腾的传热性能及其分析.实验工质为R-113.结果表明:JK-1管降膜沸腾传热膜系数比其池式沸腾提高11—80%,比光滑管降膜沸腾提高1.7—5.2倍.通过分析,建立了一个预测值与实验值偏差在±8%以内的准则关联式.

Abstract: The present paper describes a study of spray falling film boiling on horizontal mechanically made porous surface tubes (JK-1 tubes). R-113 was used as the working fluid. The results indicated that there was a 11-80% increase of heat transfer coefficients for falling film boiling on the enhanced lubes in comparison with those of their pool boiling; and there was a 2.7-6.2 times increase in comparison with those for falling film boiling on a smooth tube. Based on the analysis, a correlation was proposed which could predict spray falling film boiling heat transfer coefficients for horizontal mechanically made porous surface tubes within a relative deviation of±8%.
