AN EXPERIMENTAL STUDY OF R113 FILM CONDENSATION ON HORIZONTAL INTEGRAL-FIN TUBES.

Author(s) : MARTO P. J.

Type of article: Article

Summary

HEAT TRANSFER MEASUREMENTS WERE MADE AT NEAR-ATMOSPHERIC PRESSURE ON A SMOOTH TUBE MADE OF COPPER, ON 24INTEGRAL-FIN TUBES HAVING MACHINED, RECTANGULAR-SHAPED FINS, AND ON A COMMERCIAL INTEGRAL-FIN TUBE. THE VAPOUR FLOWED VERTICALLY DOWNWARD WITH A NOMINAL VELOCITY OF 0.4 M/S. THE VAPOUR-SIDE HEAT TRANSFER COEFFICIENT OF THE INTEGRAL-FIN TUBES WAS ENHANCED CONSIDERABLY MORE THAN THE SURFACE AREA ENHANCEMENT PROVIDED BY THE FINS. HEAT TRANSFER ENHANCEMENTS UP TO AROUND 7 WERE MEASURED FOR A CORRESPONDING AREA ENHANCEMENT OF 3.9. THE OPTIMUM FIN SPACING WAS BETWEEN 0.2 AND 0.5 MM.
