摘要：

A thermal boundary condition model at the boundary adjacent to an impermeable wall was developed for the local thermal non-equilibrium (LTNE) model for convection heat transfer in porous media. The model was validated by comparison with pore-scale numerical simulations and macro-scale LTNE model numerical simulations. The concept of the tangential interfacial thermal resistance was developed to explain the mechanism for the splitting of the heat flux between the solid and fluid phases at the wall.
