Abstract

This chapter provides a brief introduction to the upscaling of heat transfer in composite materials and porous media. Heat transfer in multi-phase, multi-scale systems is a complex phenomenon characterized by various spatial and time scales. This results in different macro-scale models. The major classes are represented by local equilibrium models for a mixture temperature close to each intrinsic phase average temperature and non-equilibrium models that relax the constraint of local equilibrium. Several properties can be inferred for the values of the effective thermal conductivity. The first property of importance is the existence of bounds in terms of the thermal conductivity ratio and volume fractions. The case of heat transfer with an interfacial thermal resistance is very important for composite material applications because of the dramatic effect it may have on the effective thermal conductivity and other effective parameters.
