A method is proposed for the evaluation of the interfacial conduction heat transfer coefficient in two-temperature macroscopic models of homogeneous fluid-saturated porous media. It is based on the numerical solutions of a microscopic model of unsteady conduction heat transfer in periodic unit cells, ...
This situation can be illustrated by considering a small, spherical object at an initial temperature T0 which is suddenly submerged in a fluid at temperature T∞ which imposes a heat transfer coefficient at the surface of the sphere h with the units W/m2K. If the sphere has density ρ, ...

The determination of the space- or time-dependent heat transfer coefficient which links the boundary temperature to the heat flux through a third-kind Robin boundary condition in transient heat conduction is investigated. The reconstruction uses average surface temperature measurements. In both cases of...
