Pore-scale modeling using TOUGH2
TOUGH2 is a porous media code which is widely-used for simulating flow and transport in fractured and porous media. TOUGH2 is generally employed using REV (Representative Elementary Volume) size elements or larger volumes. However, because TOUGH2 solves mass, momentum, and energy conservation equations, it can also be used for any size volumes as long as the proper constitutive relationships are included. The present paper discusses application of TOUGH2 to pore-scale modeling of enhanced vapor diffusion in porous media, and the changes and approximations that were employed.
