Forced Convective Heat Transfer Enhancement in a Tube with its Core Partially Filled with a Porous Medium

Forced Convective Heat Transfer Enhancement in a Tube with its Core Partially Filled with a Porous Medium

Forced convection in a tube with its core partially filled with a porous medium is treated both analytically and numerically to find its high heat transfer performance. Assuming a fully developed flow subject to a constant heat flux, both friction factor and Nusselt number are presented explicitly as functions of the Reynolds number, Darcy number and porous core diameter ratio. Partial filling ...

Thermal Non-Equilibrium Forced Convective Flow in an Annulus Filled with a Porous Medium

In light of a local thermal non-equilibrium model, fully developed forced convection in an annulus filled with a porous medium is treated to elucidate its exact temperature solutions for both fluid and solid phases. In this study, the plug-flow approximation is assumed since Darcian velocity over the cross-section is uniform except in a small region very close to the walls. The inner wall is he...

Heat transfer to MHD oscillatory dusty fluid flow in a channel filled with a porous medium

In this paper, we examine the combined effects of thermal radiation, buoyancy force and magnetic field on oscillatory flow of a conducting optically thin dusty fluid through a vertical channel filled with a saturated porous medium. The governing partial differential equations are obtained and solved analytically by variable separable method. Numerical results depicting the effects of various em...

Non-Darcy Forced Convective Heat Transfer in a Channel Embedded In a Non-Newtonian Inelastic Fluid-Saturated Porous Medium

The present analysis investigates non-Darcy forced convective heat transfer in a channel confined by two parallel walls subjected to uniform heat flux in a highly porous medium saturated with a non-Newtonian power-law fluid. Extensive numerical integrations have been carried out utilizing the Brinkman-Forchheimer extension of the Darcy model in order to study the effects of pseudoplasticity, an...
