Flow and Heat Transfer Study of an Annulus Partially Filled with Metallic Foam on Two Wall Surfaces Subject to Asymmetrical Heat Fluxes

Abstract The current research deals with the fully developed forced convection through metallic foam partly filled annulus. A was adhered to inner and outer walls of annulus in such a way that two regions one open region were formed against fluid flow. surfaces exposed an asymmetric heat flux ratio. To couple transfer flow regions, no-slip coupling conditions considered at fluid–solid interface. Based on assumption, momentum, continuity, energy equations for simplified ordinary differential solved numerically as governing equations. impact porosity, pore density, ratio conductivity, Re number, velocity profiles, temperature distributions, heterogeneity, friction factor, Nu, system performance included obtained. obtained results indicated Nu depend crucially thickness foam, density. study found partially cases had lower than empty across various number fixed conductivity 0.01, but depended When k r values below 0.002, outperformed one, annulus, this critical increased 0.006.
