The capillary pressure-saturation relation is one of the key constitutive equations used for modeling multiphase (or partially saturated) flow in porous materials. It is known that this empirical relation depends strongly on dynamic conditions, but t

Low salinity waterflooding has proven to accelerate oil production at core and field scales. Wettability alteration from a more oil-wetting to a more water-wetting condition has been established as one of the most notable effects of low salinity wate

Simultaneous pressure and electro-osmosis driven flow in charged porous media: Pore-scale effects on mixing and dispersion

Electrokinetic effects in porous media play a key role in a number of natural and industrial processes. Applications such as enhanced oil recovery, soil remediation and even drug delivery are affected by the Coulombic forces created by the solid-flui

Effect of divalent ions on the dynamics of disjoining pressure induced by salinity modification

Autor: Vahid Niasar, Omar E. Godinez-Brizuela

Publikováno v: Journal of Molecular Liquids. 291:111276

Disjoining pressure is defined as the net difference between the pressure in a water film and that of the bulk fluid. It is known that disjoining pressure in water films is one of the thermodynamic aspects that control wettability, and is itself loca
