... a positive effect on heat transfer rate at first fin for each parameter and at second fin for all Prandtl numbers and high Reynolds numbers. But at outlet fin the porous medium has negative effect on heat transfer rate except Pr = 5. Finally, it is found that by reducing porosity, the heat exchanger reaches...
