Abstract

Abstract

Entropy generation for thermally developing forced convection in a porous medium bounded by two isothermal parallel plates was investigated analytically on the basis of the Darcy flow model where the viscous dissipation effects had also been taken into account.A parametric study showed that decreasing the group parameter and the P clet number increases the entropy generation while for the Brinkman number the converse is true.Heatline visualization technique is applied with an emphasis on Br is less than 0 case where there is somewhere that heat transfer changes direction at some streamwise location to the wall instead of its original direction,i.e.from the wall.
