- •
Porous media can improve the coefficient of heat transfer up to 2.2 fold.
- •
Both porous media and Nano particles have undesired pressure drop effect.
- •
Application of both porous media and magnetic field in ferrofluid flow will result in significant enhancement in heat transfer up to 2.4 fold.
- •
Magnet bar effect is mainly restricted to approximately one fourth of the test section.
- •
Diluted Ferrofluids 2%, results in over 1.4 fold enhancement in heat transfer coefficient.
