Summary

A MODEL IS DEVELOPED FOR PREDICTION OF THE CONDENSATION COEFFICIENT ON HORIZONTAL INTEGRAL-FIN TUBES FOR BOTH HIGH AND LOW SURFACE TENSION FLUIDS. IT INCLUDES THE EFFECTS OF SURFACE TENSION ON FILM DRAINAGE AND ON CONDENSATE RETENTION BETWEEN THE FINS. TYPICALLY, THE CONDENSATION COEFFICIENT IN THE FLOODED REGION IS NEGLIGIBLE. THE CONDENSATION COEFFICIENT ON THE UNFLOODED PORTION IS CALCULATED. THE MODEL IS USED TO PREDICT THE R11 CONDENSATION COEFFICIENT. THE PREDICTED VALUES ARE WITHIN ABOUT 20 PERCENT OF THE EXPERIMENTAL VALUES.
