Influence of Disorder Strength on Phase Field Models of Interfacial Growth
T. Laurila, M. Pradas, A. Hernandez-Machado +1
We study the influence of disorder strength on the interface roughening process in a phase-field model with locally conserved dynamics. We consider two cases where the mobility coe…
Dynamical scaling of imbibition in columnar geometries
M. Pradas, A. Hernández-Machado, M. A. Rodríguez
Recent experiments of imbibition in columnar geometries show interfacial fluctuations whose dynamic scaling is not compatible with the usual non local model governed by surface ten…
Polymer-induced tubulation in lipid vesicles
F. Campelo, A. Hernandez-Machado
A mechanism of extraction of tubular membranes from a lipid vesicle is presented. A concentration gradient of anchoring amphiphilic polymers generates tubes from bud-like vesicle p…
Three-dimensional aspects of fluid flows in channels. II. Effects of Meniscus and Thin Film regimes on Viscous Fingers
R. Ledesma-Aguilar, I. Pagonabarraga, A. Hernandez-Machado
We perform a three-dimensional study of steady state viscous fingers that develop in linear channels. By means of a three-dimensional Lattice-Boltzmann scheme that mimics the full…
Three-dimensional aspects of fluid flows in channels. I. Meniscus and Thin Film regimes
R. Ledesma-Aguilar, A. Hernandez-Machado, I. Pagonabarraga
We study the forced displacement of a fluid-fluid interface in a three-dimensional channel formed by two parallel solid plates. Using a Lattice-Boltzmann method, we study situation…
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…
