A numerical experiment has been conducted to determine the interfacial convective heat transfer coefficient in the two-energy equation model of porous media, which is needed when the assumption of the local thermal equilibrium between the fluid and solid phases is not valid. Three fundamental case, in which the assumption of local equilibrium fails, were treated using structural models of porous media, to determine the interfacial heat transfer coefficient without any empiricism. A universal correlation for the Nusselt number, which agrees very well with the experimental data, has been established using the results obtained for a wide range of porosity, Prandtl and Reynolds numbers.
