A Note on Local Thermal Non-Equilibrium in Porous Media Near Boundaries and Interfaces

摘要

Recent work on what has been called the phenomenon of heat flux bifurcation, that occurs at a boundary of a porous medium, or at an interface with a fluid clear of solid material, when a two-temperature model for the porous medium is employed, is discussed. An alternative interpretation of the situation, one in which the physics of the problem is emphasized, is presented.
