Published in: Proceedings of International Journal of Refrigeration
Abstract: An experimental investigation has been carried out to study the condensation of R-134 vapour over five single horizontal circular integral-fin tubes of 472fpm fin density, 417 mm length and different fin heights of 0.45, 1.14, 1.47, 1.92 and 2.40 mm. The circular fins are rectangular in shape and the fin thickness of all tubes is 0.70 mm. The tube with the fin height of 0.45 mm has given the highest enhancement in heat transfer coefficient, h, of the order of 3.18 in comparison to that predicted by the Nusselt model for a plain tube. © 2004 Elsevier Ltd and IIR.
