yes you can.
generally, the porous media used in force convection to increase heat transfer, While it used in natural convection to decrease heat transfer (insulation).

it is difficult due to the fin with a very thin thickness, numerically it possible.
Laith M. Jasim actually i need sth with high porosity (more than 85%) and high thermal conductivity (in the range of metals' properties) which can be used in the mentioned scale and could have enough stability against water liquid momentum.
thank u.
Md. Washim Akram i appreciate u. but the thermal conductivity in ur suggested articles is too low and it can not be useful for heat transfer enhancement. thanks a lot.
Abbas J Jubear yes i think so. i want to study numerically about that. but i am curious to know that how close is that to experimental?
It is possible to have a fin with specific characteristics analytically and numerically.
It is too easy. Fint out the corrugated fin heat exchanger with my paper.
Sangrae Lee i need flow penetrate into the fins and be connected with flows in adjacent channels. ur corrugated fins increase pressure drop...
There is also a straight fin for the purpose of lowering the drop in pressure loss.
It's need to find out "straight fin or plain fin" from google.
