Zusammenfassung:One of the interesting subjects in reactor design is about the condensate flow. In this investigation, turbulent film condensation on a horizontal elliptical tube is investigated using volume of fluid (VOF) method. Heat transfer after the separation point is considered. The turbulence model incorporated in this investigation is the realizable k-epsilon model. The results for circular tube are compared to that of other investigations available in the literatures. It is observed that an amount of approximately 11% decrease in the overall Nusselt number will happen for the elliptical tube with respect to a circular tube of the same area and the same approach velocity.
