So, certainly
the formulation is based on multiphase, multi-species approach. And the
porous medium is assumed to be of mineral, water and air, and then you have
solid, liquid and gas. So you have heat transfer by heat conduction, and then the heat advection because of liquid water, then you have liquid advection because of water vapour and then you have gases air, you have phase changes, then a water flow because of the heat liquid phase advection, then you have water phase diffusion, advection, diffusion, and then you have mechanical behaviour, because it also depends on the stress action and the temperature. | ![]() |
