Numerical Simulation of Drying of a Deformable Anisotropic Porous Medium Using the Lattice Boltzmann Method

The convective drying of an anisotropic saturated deformable porous media has been carried out numerically in the present paper based on the Darcy-Brinkmann extended model. The considered sample is a porous medium that is assumed to be both hydro-dynamically and thermally anisotropic. All walls of the sample are subjected to a convective heat flux. Furthermore, the thermal equilibrium condition is assumed to be applicable to the current investigation. The principal axis of the anisotropic porous medium ranges between 0 and 90°. The Lattice Boltzmann method (LBM) is used to solve the differential equation system. Special attention is given throughout this work to understand the effect of dynamic and thermal anisotropic parameters and the mass boundary conditions on macroscopic fields.
