Effect of a Circumferential Rib on Film Condensation on a Horizontal Two-Dimensional Fin Tube
RÉSUMÉ
The effect of a circumferential rib on the condensation heat transfer performance of a horizontal two-dimensional fin tube was studied numerically. Numerical calculation was performed for systematically changed values of rib parameters with HCFC-123 as a working fluid. Numerical results showed that circumferential ribbing is effective in enhancing film condensation. The effect was more significant for a double rib fin than for a single rib fin. For a typical combination of geometrical parameters of the fin, the average heat transfer coefficient was about 58 and 27% higher with the double rib fin and the single rib fin, respectively, than with the best performing fin profile proposed in previous studies.
