Thermal study of fluid flow inside an annular pipe filled with porous media under local thermal non-equilibrium condition

Slip flow in porous micro-tubes under local thermal non-equilibrium conditions

In the present work, forced convection heat transfer of slip flow in porous micro-tubes with local thermal non-equilibrium between the gas and the solid matrix is investigated numerically. For this purpose, the flow is considered hydrodynamically developed but thermally developing. The Darcy-Brinkman-Forchheimer model in conjunction with separate energy equations for the gas and the solid matri...

Analysis of thermally developing flow in porous media under local thermal non-equilibrium conditions

In the present study, analytical solutions for thermally developing flows in porous media under local thermal non-equilibrium (LTNE) condition are derived for different fundamental models. The analytical solutions are validated by comparison with the numerical results. Based on the analytical solutions, the local Nusselt number is obtained, and the dimensionless thermal entry length nc is predi...

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...
