Numerical Modelling of Two-Phase Flow in Fractured Rock Masses Using Zero-Thickness Interface Elements

In recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into account explicitly the effect of fractures and discontinuities in the fluid flow as well as the effect of fluid pressure in...
