Session 28: Porous Media: transport, microstructural evolution, multi-physics coupling and instabilities
Conveners : Henri Bertin, Giulio Sciarra, Benoit Rousseau, Gérard Vignoles
This session aims to bring together academic and industrial researchers to present recent scientific advances in the study of the behavior of porous media, whether they are geomaterials, man-made or natural materials. The session aims to focus on the development and identification of effective constitutive laws in porous media, under different stresses of physical, chemical, thermal and / or mechanical nature, studied separately or coupled. Research on transport phenomena (conductive / diffusive, convective / advective, ballistic / radiative) is a central topic of this session, as well as studies on the evolution of the microstructure of a porous medium (dissolution / precipitation, chemical reactions of deposition / ablation / erosion, mechanical deformations, localization, damage, etc.). This microstructural evolution can be analyzed at the local scale, integrated into a macroscopic formulation or studied experimentally. In addition, instabilities due to non-linearities and / or couplings between elementary phenomena, which may be linked to interfaces, natural convection, deformations or others, at different scales of porous media, are a focal research topic of this session.
