Abstract: This study deals with drying modeling of a partially saturated deformable porous media (solid, liquid, and gas phases). In fact, during their drying, the deformable porous media undergo stresses due to volume shrinkage. The objectives of the model are to foresee the mechanical stresses in order to control the deformations of the product. Modeling of drying has been worked out for saturated media as well as for unsaturated media. The problem deals with the level of the transition between saturated and unsaturated medium where a continuous physical modeling does not exist currently. In this work, a mathematical model is proposed to describe the heat, mass, and momentum transfers applied to the drying of an unsaturated and deformable medium. The pressure gradient is the main driving force for the water migration through Darcy's law. The particularity of the model is that it takes into account the strong coupling between mass transport and mechanical behavior of the material while using the notion of effectiv...

Effects of Anisotropy and Drying Air Parameters on Drying of Deformable Porous Media Hydro-Dynamically and Thermally Anisotropic
TL;DR: In this paper, the authors investigated numerically the drying of saturated deformable porous media, which is assumed to be both hydro-dynamically and thermally anisotropic, while the mechanical behavior of the sample is supposed to be isotropic.

BI-CGSTAB: a fast and smoothly converging variant of BI-CG for the solution of nonsymmetric linear systems
TL;DR: Numerical experiments indicate that the new variant of Bi-CG, named Bi- CGSTAB, is often much more efficient than CG-S, so that in some cases rounding errors can even result in severe cancellation effects in the solution.
