HYDRODYNAMIC BEHAVIORS OF AN ISOTROPIC DEFORMABLE POROUS MEDIA USING THE LATTICE BOLTZMANN METHOD

摘要

The present investigation centered around the evolution of hydrodynamic behaviors during drying of a saturated deformable porous media using the Lattice Boltzmann method (LBM). The physical model used for this study is an isotropic deformable porous plate saturated with a fluid phase (water). All walls of the sample are maintained to a convective heat flux. The top and bottom walls are also subjected to a mass flux. The liquid flow is modeled by the Darcy-Brikmann extended model. The deformation of the solid phase is deduced from the principle momentum conservations based on the same model coupled to the terzaghi theory. The model for the energy equation was based on the local thermal equilibrium assumption, between the liquid and the solid phases. A comprehensive analysis of the influence of the drying air parameters on the hydrodynamic behaviors is investigated throughout this work.
