Entropy Generation Minimization in a Vertical Porous Channel

Abstract

This chapter is mainly focused on the minimization of the total entropy generation in a thermodynamic system, which concerns the heating of water when it passes through a saturated porous media. The heating process is assumed by an array of heating tubes immerged on the porous media and perpendicular to the water flow direction. This irreversibility calculation and minimization is carried out in dimensional form in order to have a real idea about the entropy production in the system. Also, the authors focus on several points regarding the rigor of entropy generation calculation, when they pass from dimensional form to dimensionless form.
