Abstract: The paper considers the mechanism of reducing the permeability of aqueous graphene suspension through the oil-saturated core compared to distilled water. Analysis of experimental data shows that an increase in permeability is due to the formation of corrugated films at the interface between two immiscible fluids during their mutual motion. The appearance of wavy surfaces is the result of Kelvin–Helmholtz instability at the grapheme–nanofluid–hydrocarbon interface. It is also shown that the occurrence of instability is possible only in the presence of a transition layer–graphene film.
Keywords: graphene nanofluid, graphene film, corrugated surface, porous medium.
