A theoretical study of entropy generation of the combustion phenomenon in the porous medium burner

In this paper, a symmetric two-dimensional numerical model for premixed methane-air combustion in a porous medium has been developed. For this purpose, multi-step mechanisms and variable porosity have been used and the effects of them on the entropy generation rate have been investigated. This model solves the continuity, Navier Stokes, the solid and gas energy, the chemical species transport equations and entropy generation rate equations by...
