heal.abstract	A pore network model for the drying of capillary porous media is presented in this work. The model accounts for various processes at the pore scale including evaporation of a volatile liquid, mass transfer of the vapors by advection and diffusion in the gas phase and viscous flow in the liquid and gas phases. Both viscous and capillary forces at the liquid menisci in pore throats are also modeled. We consider isothermal drying in a rectilinear horizontal geometry, with no flow conditions in all but one boundary, at which a purge gas is injected at a constant rate. Drying rates, phase distribution and concentration patterns are reported as a function of time and the gas flow rate. We also refer to the evolution of trapped liquid clusters.	en
