Coupled thermo-hydro-mechanical (THM) process in saturated porous media has been the subject of numerous studies. Recently, the influence of temperature gradient on the mass balance of fluid has been analyzed through the “thermo-osmosis effect” in low permeable soils, e.g., clay. In the case of thermal pore pressurization, the thermo-osmosis phenomenon causes the fluid flows away from the heat source and therefore alters the excess pore water pressure diffusion directly. Previous studies have shown that to better predict the thermal pressurization and thermal response of clayey soil, the thermo-osmosis phenomenon should be considered. Therefore, in the current study, a THM model with strong coupling is implemented in COMSOL multiphysics finite element software to assess the effect of thermo-osmotic flow in a saturated porous medium. The numerical results are compared with the experimental measurement of heating in Boom clay. The results show that thermo-osmotic flow leads to lower thermal pressurization in the vicinity of the heater; however, it does not affect the temperature distribution in the soil.
