The displacement of two fluids in a porous medium can be affected by a viscous fingering instability (VF) that arises at the interface between the fluids when their viscosities are different. In parallel, one of the fluids ...

The effect of a linear adsorption isotherm on the onset of fingering instability in a miscible displacement in the application of liquid chromatography, pollutant contamination in aquifers, etc., is investigated. Such ...
