A numerical study on Saffman-Taylor instability of immiscible viscoelastic-Newtonian displacement in a Hele-Shaw cell
2018, Journal of Non-Newtonian Fluid MechanicsCitation Excerpt :Despite the importance of surface tension in viscous fingering phenomenon, only a few studies have been conducted in immiscible non-Newtonian displacement. Pascal [40,41] performed a theoretical analysis of the viscous fingering instability in shear-thinning fluids. All of the investigations have performed for immiscible liquids and the power-law model, using the constitutive equations.
Saffman–Taylor instability of viscoelastic fluids in anisotropic porous media
2018, International Journal of Mechanical SciencesCitation Excerpt :The vast majority of these studies have focused on the role of shear-thinning fluid in this instability and the effect of elasticity has been ignored. Pascal [23–25] was among those who investigated the fingering instability that displacing or displaced fluids were shear-thinning fluids. He used the power law model to show the shear-thinning behavior of non-Newtonian fluids.
Displacement of yield-stress fluids in a fracture

2013, International Journal of Non-Linear MechanicsCitation Excerpt :Pascal [11] adopted Muskat’s frontal advance model to study steady-state immiscible displacement of a Bingham fluid by another in plane/radial geometry. Steady-state displacement, and its stability, were analyzed in Ref. [12] for power-law fluids with yield stress in plane geometry, and in Ref. [13] for power-law fluids in radial geometry; capillarity was added to the model in Ref. [14]. In Ref. [15], transient plane displacement of a power-law compressible fluid by another was considered.
