Entropy generation minimization in film condensation on a flat plate with interfacial shear stress

This study focuses on the second law analysis of film condensation on a flat plate. Based on the interfacial shear and the gravitational forces applied to the liquid film, two limiting cases are investigated. Finally, a general expression for total entropy generation is derived as a function of liquid film thickness and the effects of the two forces on total entropy generation rate are discussed. Using entropy generation minimization method (EGM), the existence of an optimum condition for each case is discussed.
