Abstract
The aim of this study is to analyze the entropy generation number in forced convection film condensation on a horizontal isothermal elliptical tube. A numerical approach has been used to investigate how parameters, including ellipticity of ellipse, Reynolds and Brinkman numbers affect the irreversibility. The results show that the minimization of total entropy generation number (NS ) can be achieved by reducing the values of Reynolds and Brinkman numbers. Also, it was concluded that the effect of ellipticity on total entropy generation number is significant for e > 0.7 and increasing ellipticity, increases the amount of NS.
