Résumé :
|
The boiling heat transfer on a finned tube bundle was experimentally studied in R11 at a pressure of 1 bar. The results indicate that the boiling heat transfer is strongly enhanced by the strong two-phase flow induced by the tubes of the lower rows, especially in the intermediate region, with the maximum enhancement of heat transfer relative to that with the lower rows not heated was as much as 150%.
