Abstract

A numerical study optimized the thermal performance ofan aluminium tube filled with porous media metal foam.The investigation analyzed four aluminium metal foammodels, including those with and partially filled metalfoam and multi-layered metal foam of differentporosities. The multi-layer porosities, which represent adual permeability setup, specifically. The porosity ofmetal foam varies from 0.9 to 0.92, and the pore density(PPI) varies from 10 to 30 PPI. The Darcy-ExtendForchheimer model was used for flow dynamics withinthe porous region. The local thermal non-equilibriummodel was applied within the porous-filled region of thepipe to analyze heat transfer characteristics. The resultsshowed that the thermal performance of a fully filledporous metal foam structure is superior to that of apartially filled structure. As well as multi-layer porositiesof aluminium metal foam exhibited greater thermalefficiency than single layers.
