| Abstract: | In this paper, the second law analysis of a laminar falling viscous incompressible liquid film along an inclined porous heated plate is investigated. The upper surface of the liquid film is considered free and adiabatic. Based on some simplifying assumptions, analytical solutions for the fluid velocity and temperature are constructed. The expressions for the entropy generation rate and irreversibility ratio are obtained and the results are presented graphically and discussed quantitatively for several values of suction Reynolds number (Re) and group parameter (BrΩ−1). |
