Heat Transfer In Porous Media: Various Models From A Multi-Scale Perspective
Heat transfer in porous media is a typical example of complex multi-scale problem with multiphase aspects, potential for local non-equilibrium behaviors, strong coupling with other transport mechanisms (multiphase flow, dispersion, reaction, …). Applications are found in many different areas, bringing also a large spectrum of characteristic spatial and time scales: chemical engineering, nuclear engineering, petroleum engineering, geothermal resources, composite materials, ablative layers in aerospace industry, drying and food engineering, cryogenic engineering, to name a few. As a consequence of this diversity, various models may be developed to handle local equilibirum or local non-equilibrium flows and the different couplings. In the first part, the course objective is to give an advanced presentation of the various models for the simple case of one-phase flow in a porous medium: 1 to N-equation models, hybrid or mixed models, with indications on how to calculate or estimate effective properties. In the second part of the course, additional problems will be dealt with: weak couplings, interfacial thermal resistance, homogeneous and heterogeneous heat sources, coupling with dispersion (Soret effect) and strong couplings (combustion, pyrolysis), phase change (drying, boiling). The lectures will be illustrated by examples coming from the various applications cited above.
