Background: The unique structural characteristics of the metal foams, such as low density,
large surface area, ability to increase turbulence, and increased heat transfer efficiency, are the advantages
associated with thermal applications such as electronics cooling, refrigeration air conditioning,
etc. The porous metal foam structures are extensively used to enhance heat transfer.
Objective: This paper discusses the numerical simulations of a vertical channel filled with metal foam
and wire mesh. The fluid flow and heat transfer phenomena of a wire mesh are compared with two
different types of metal foams. Metal foams are made of aluminium and copper while the wire mesh is
made of brass. The porosity of the metallic porous structures varies from 0.85 to 0.95.
Methods: A Darcy extended Forchheirmer model is considered for solving fluid flow through the
porous media while the heat transfer through the porous media is predicted using local thermal
Results: Initially, the results obtained using the proposed numerical procedures are compared with
experimental results available in the literature. The numerical simulations suggest that the pressure drop
increases as the velocity of the fluid increases and decreases as the porosity increases. The heat transfer
coefficient and Nusselt number are determined for both the metal foams and the wire mesh.
Conclusion: The Nusselt number obtained for wire mesh shows almost 90% of the copper metal foam
in the same porosity range. The numerical results suggest that the brass wire mesh porous medium can
also be used for enhancement of heat transfer. In this article, patents have been discussed.
