| 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%. |
