The second law analysis of heat transfer of a non-Newtonian, laminar fallingliquid film along an inclined heated plate is investigated. The upper surface of the liquidfilm is considered free and adiabatic. Velocity and temperature profiles are obtainedanalytically and used to compute the entropy generation number (Ns), irreversibility ratio (Φ) and the Bejan number (Be) for several values of the viscous dissipation parameter(Br -1), viscosity index (n) and the dimensionless axial distance (X). The Bejan numberincreases in the transverse direction and decreases as the viscous dissipation parameter(BrΩ -1) increases. The numerical results show that the Bejan number decreases as theviscous dissipation parameter (BrΩ -1), Peclet number (Pe) and the viscosity index (n)increase. View Full-Text
