Manipulating heat flux bifurcation & dispersion inside porous media for heat transfer control

A method for analyzing heat flux bifurcation inside a porous medium, said method comprising:

• analyzing convective heat transfer within a channel partially filled with a porous medium under a local thermal non-equilibrium condition;
• determining at least one solution for a fluid temperature distribution and a solid temperature distribution;
• deriving a Nusselt number solution for three interface thermal models at a porous-fluid interface with respect to said porous medium;
• determining local thermal equilibrium conditions with respect to said porous medium by utilizing an average temperature difference between a fluid phase and a solid phase within said porous medium;
• analyzing convective heat transfer within the composite system which consists of porous media and adjacent open regions under a local thermal non-equilibrium condition;
• and
• measuring the interstitial heat transfer coefficient between fluid and solid phases in porous media in the presence of the heat flux bifurcation.
