Vesicle formation induced by thermal fluctuations
Andreu F. Gallen, J. Roberto Romero-Arias, Rafael A. Barrio +1
The process of fission and vesicle formation depends on the geometry of the membrane that will split. For instance, a flat surface finds it difficult to form vesicles because of th…
Theory of wetting-induced fluid entrainment by advancing contact lines on dry surfaces
Rodrigo Ledesma-Aguilar, Aurora Hernández-Machado, Ignacio Pagonabarraga
We report on the onset of fluid entrainment when a contact line is forced to advance over a dry solid of arbitrary wettability. We show that entrainment occurs at a critical advanc…
Growth saturation of unstable thin films on transverse-striped hydrophilic-hydrophobic micropatterns
Rodrigo Ledesma-Aguilar, Aurora Hernandez-Machado, Ignacio Pagonabarraga
Using three-dimensional numerical simulations, we demonstrate the growth saturation of an unstable thin liquid film on micropatterned hydrophilic-hydrophobic substrates. We conside…
Dynamics of gravity driven three-dimensional thin films on hydrophilic-hydrophobic patterned substrates
Rodrigo Ledesma-Aguilar, Aurora Hernandez-Machado, Ignacio Pagonabarraga
We investigate numerically the dynamics of unstable gravity driven three-dimensional thin liquid films on hydrophilic-hydrophobic patterned substrates of longitudinal stripes and c…
Shape instabilities in vesicles: a phase-field model
F. Campelo, A. Hernandez-Machado
A phase field model for dealing with shape instabilities in fluid membrane vesicles is presented. This model takes into account the Canham-Helfrich bending energy with spontaneous…
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…
