Second-Law Analysis of Thermally Developing Forced Convection in a Porous Medium

ABSTRACT

Entropy generation for thermally developing forced convection in a porous-saturated circular tube of uniform wall temperature is 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 Péclet number increases the entropy generation while for the Brinkman number the converse is true.
