Résumé

The study was conducted for plain tubes, circular integral-fin tubes (CIFTs), spine integral-fin tubes (SIFTs) and partially spined circular integral-fin tubes (PCIFTs) The SIFT outperformed the CIFT for the condensation of R134a by approximately 16%. However, the spines were found most effective in the bottom side of the CIFT. The PCIFTs with the spines only in the bottom side of the tube augmented the heat transfer coefficient by 20% and 11% for the condensation of steam and R134a, respectively, in comparison to the CIFT.
