Thin films dewetting with phase separation: Dependence of surface tension and Hamaker constant on concentration
Javier A. Diez, Alejandro G. González, Lou Kondic
We study the instability of a thin film composed of two miscible fluids (binary fluid) placed on a solid planar surface. We include the fact that both the free surface and wetting…
Equilibrium solutions of a sessile drop partially covered by another liquid
Pablo D. Ravazzoli, Alejandro G. González, Javier A. Diez
We study the equilibrium solutions of a sessile drop on top of a horizontal substrate when it is partially covered by another inmiscible liquid, so that part of the drop is in cont…
Buoyancy and capillary effects on floating liquid lenses
P. D. Ravazzoli, A. G. González, J. A. Diez +1
We study the equilibrium shape of a liquid drop resting on top of a liquid surface, i.e., a floating lens. We consider the surface tension forces in non--wetting situations (negati…
Contact angle hysteresis effects on a drop sitting on an incline plane
Pablo D. Ravazzoli, Ingrith Cuellar, Alejandro G. González +1
We study the contact angle hysteresis and morphology changes of a liquid drop sitting on a solid substrate inclined with respect to the horizontal at an angle . This one is alwa…
Self-assembly of a drop pattern from a two-dimensional grid of nanometric metallic filaments
Ingrith Cuellar, Pablo D. Ravazzoli, Javier A. Diez +5
We report experiments, modeling and numerical simulations of the self--assembly of particle patterns obtained from a nanometric metallic square grid. Initially, nickel filaments of…
Drop pattern resulting from the breakup of a bidimensional grid of liquid filaments
Ingrith Cuellar, Pablo D. Ravazzoli, Javier A. Diez +1
A rectangular grid formed by liquid filaments on a partially wetting substrate evolves in a series of breakups leading to arrays of drops with different shapes distributed in a rat…
Wetting and dewetting processes in the axial retraction of liquid filaments
Pablo D. Ravazzoli, Ingrith P. Cuellar, Alejandro G. González +1
We study the hydrodynamic mechanisms involved in the motion of the contact line formed at the end region of a liquid filament laying on a planar and horizontal substrate. Since the…
Drops with non-circular footprints
Pablo D. Ravazzoli, Alejandro G. González, Javier A. Diez
In this paper we study the morphology of drops formed on partially wetting substrates, whose footprint is not circular. This type of drops is a consequence of the breakup processes…
Thin film instability with thermal noise
Javier A. Diez, Alejandro G. González, Roberto Fernández
We study the effects of stochastic thermal fluctuations on the instability of the free surface of a flat liquid film upon a solid substrate. These fluctuations are represented as a…
Inertial and dimensional effects on the instability of a thin film
A. G. González, J. A. Diez, M. Sellier
We consider here the effects of inertia on the instability of a flat liquid film under the effects of capillary and intermolecular forces (van der Waals interaction). Firstly, we p…
