THEORETICAL AND EXPERIMENTAL INVESTIGATION OF CONDENSATION HEAT TRANSFER AND ITS ENHANCEMENT OUTSIDE A HORIZONTAL FINNED TUBE.

Author(s) : LI Y., WU Q.

Summary

A NEW METHOD TO ENHANCE CONDENSATION HEAT TRANSFER OUTSIDE HORIZONTAL FINNED TUBE IS PRESENTED BY ATTACHING A GUIDING STRIP TO THE BOTTOM OF TUBE. TWO KINDS OF STRIPS AND TWO TYPES OF ATTACHING METHODS WERE ADOPTED FOR COMPARISON WHILE CONDENSING R11 IN THE EXPERIMENT. THE AVERAGE HEAT TRANSFER COEFFICIENT WAS CONSIDERABLY INCREASED BY ATTACHING A GUIDING STRIP, WHICH IS TO ALLOW THE CONDENSATE ACCUMULATING IN THE BOTTOM OF FIN-TUBE TO SEPARATE FROM TUBE WALL EASILY. THE MAXIMUM INCREASE OF HEAT TRANSFER COEFFICIENT IS 20% BY EXPERIMENTAL INVESTIGATION AND 30% BY THEORETICAL ANALYSIS IN THE HEAT FLUX RANGE OF 4,000-18,000 W/M2.
