Coupled thermo-hydro-mechanical model with consideration of thermal-osmosis based on modified mixture theory

A coupled formulation based on non-equilibrium thermodynamics, Biot’s elasticity is derived to model thermal-osmotic flow in very low permeability rock. Darcy’s law has been modified by incorporating thermal effects from the dissipation process by using standard arguments of non-equilibrium therm...
