Abstract
The present paper analyzes the exergy and the entropy generation for a stationary laminar flow in a two-dimensional horizontal rectangular channel with a porous matrix. Uniform heat flux is applied at bounding walls.
The equations were treated by the code “FLUENT 6.3.26” which uses a finite volume discretization.
After the validation of the numerical method used through the experimental work of Irfan Kurtbaç et al., we examined the influence of the Reynolds number on the entropy generation, exergy, and irreversibility.
Numerical simulations are undertaken using a range of Reynolds number (600 ˂ Re ˂ 2200) and Darcy number (Da = 10−1).
The main result worth noting is that increasing the Reynolds number increases the generation of entropy, irreversibility, and exergy.
