An approximate equation for the vapour-side heat-transfer coefficient for condensation on low-finned tubes

Abstract

Simplifying approximations, together with dimensional analysis, have been used to obtain a formula for the relation between the heat flux and vapour-side temperature difference for condensation on low, integral-finned tubes. The final result involves two unknown (disposable) constants which have been determined from heat-transfer data. The resulting equation is found to be in satisfactory agreement with experimental data from 11 investigations with various condensing fluids and a range of fin and tube geometries. © 1994.
