Entropy generation in a vertical square channel packed with saturated porous
media, and subjected to differentially heated isothermal walls has been
numerically investigated.
The effect of Darcy, Reynolds, and Eckert numbers on Entropy generation was
studied. The entropy generation was found to be inversely proportional to both
Reynolds and Darcy number, while it was directly proportional with the Eckert
It was shown that as Darcy and Reynolds numbers were increasing, the Bejan
number decreases, i.e., the irreversibility due fluid friction is dominated, while as
the Eckert increases, theirreversibility due to heat transfer increases
