Summary

EXPERIMENTS WERE PERFORMED TO STUDY THE FLOW CHARACTERISTICS AND HEAT TRANSFER DURING CONDENSATION OF R11 AND R113 IN HORIZONTAL ANNULI WITH AN ENHANCED INNER TUBE. THE INNER TUBE WAS A 19.1 MM OUTER DIAMETER CORRUGATED TUBE WITH SOLDERED WIRE FINS ON THE OUTER SURFACE. THE FRICTIONAL PRESSURE GRADIENT WAS CORRELATED FAIRLY WELL BY USING THE LOCKHART AND MARTINELLI PARAMETERS. THE LOCAL HEAT TRANSFER COEFFICIENT WAS 2 TO 18 TIMES AS LARGE AS THOSE FOR HORIZONTAL ANNULI WITH SMOOTH AND CORRUGATED INNER TUBES. AN EMPIRICAL EQUATION FOR THE LOCAL HEAT TRANSFER COEFFICIENT WAS DEVELOPED.
