AB The second law analysis for the combined convective heat transfer in a non-Newtonian boundary-layer flow over a wedge embedded in a porous medium is presented. Velocity and temperature fields are solved numerically under the similarity assumption. These results are used to compute the entropy generation number N<sub>s</sub>, irreversibility ratio &#248;, and the Bejan number Be for a range of values of the viscosity index (n), streamwise distance (x), buoyancy parameter (&#955;), and viscous frictional parameter, G. The results show that the Bejan number increases with the viscosity index and the buoyancy parameter.
