Phase-field simulations of viscous fingering in shear-thinning fluids
Sebastien Nguyen, Roger Folch, Vijay K. Verma +2
A phase-field model for the Hele-Shaw flow of non-Newtonian fluids is developed. It extends a previous model for Newtonian fluids to a wide range of shear-dependent fluids. The mod…
Periodic forcing in viscous fingering of a nematic liquid crystal
R. Folch, T. Tóth-Katona, Á. Buka +2
We study viscous fingering of an air-nematic interface in a radial Hele-Shaw cell when periodically switching on and off an electric field, which reorients the nematic and thus cha…
Viscous fingering in liquid crystals: Anisotropy and morphological transitions
R. Folch, J. Casademunt, A. Hernandez-Machado
We show that a minimal model for viscous fingering with a nematic liquid crystal in which anisotropy is considered to enter through two different viscosities in two perpendicular d…
Phase-field model for Hele-Shaw flows with arbitrary viscosity contrast. II. Numerical study
R. Folch, J. Casademunt, A. Hernandez-Machado +1
We implement a phase-field simulation of the dynamics of two fluids with arbitrary viscosity contrast in a rectangular Hele-Shaw cell. We demonstrate the use of this technique in d…
Phase-field model for Hele-Shaw flows with arbitrary viscosity contrast. I. Theoretical approach
R. Folch, J. Casademunt, A. Hernandez-Machado +1
We present a phase-field model for the dynamics of the interface between two inmiscible fluids with arbitrary viscosity contrast in a rectangular Hele-Shaw cell. With asymptotic ma…
