Corrector estimates for a thermodiffusion model with weak thermal coupling. Muntean, A. & Reichelt, S. Multiscale Modeling and Simulation, 2018.

Copyright © by SIAM. Unauthorized reproduction of this article is prohibited. The present work deals with the derivation of corrector estimates for the two-scale homogenization of a thermodiffusion model with weak thermal coupling posed in a heterogeneous medium endowed with periodically arranged high-contrast microstructures. The term \weak thermal coupling" refers here to the variable scaling in terms of the small homogenization parameter " of the heat conduction-diffusion interaction terms, while the \high-contrast" is considered particularly in terms of the heat conduction properties of the composite material. As a main target, we justify the first-order terms of the multiscale asymptotic expansions in the presence of coupled fluxes, induced by the joint contribution of Sorret and Dufour-like effects. The contrasting heat conduction combined with cross coupling leads to the main mathematical difficulty in the system. Our approach relies on the method of periodic unfolding combined with "-independent estimates for the thermal and concentration fields and for their coupled fluxes.
