Abstract

Condensate flow and heat transfer enhancement aspects during laminar film condensation of pure vapours over horizontal integral-fin (HIF) surfaces are numerically analyzed. Effects of fin geometry and fluid properties are studied. Suitable non-dimensional groups are identified. Experimental data of refrigerants and steam condensing over 77 copper HIF tubes are successfully correlated for the first time in a non-dimensional form within ±15%. 1 Introduction Horizontal integral-fin (HIF) tubes, shown in Fig.l, are commonly used in horizontal surface condensers, to enhance the shell-side condensation heat transfer. Systematic experimental data on the effect of fin geometry and condensing fluid have been reported in th
