ABSTRACT
A numerical study optimized the thermal performance of an aluminium tube filled with porous media metal foam. The investigation analyzed four aluminium metal foam models, including those with and partially filled metal foam and multi-layered metal foam of different porosities. The multi-layer porosities, which represent a dual permeability setup, specifically. The porosity of metal foam varies from 0.9 to 0.92, and the pore density (PPI) varies from 10 to 30 PPI. The Darcy-Extend Forchheimer model was used for flow dynamics within the porous region. The local thermal non-equilibrium model was applied within the porous-filled region of the pipe to analyze heat transfer characteristics. The results showed that the thermal performance of a fully filled porous metal foam structure is superior to that of a partially filled structure. As well as multi-layer porosities of aluminium metal foam exhibited greater thermal efficiency than single layers.
