Viscoelasticity Enhances Contactless Adhesion of Soft Substrates
Marco Rizzo, Jacco H. Snoeijer, Vincent Bertin +1
Understanding adhesion is essential for describing stability, friction, and interfacial dynamics. Here, we investigate the adhesion force dynamics between a rigid sphere and a soft…
Transition from contact to hydrodynamic lubrication over rough surfaces
Vincent Bertin, Olivier Pouliquen
We present a theoretical analysis of frictional transitions along the Stribeck curve for rough elastic contacts lubricated by a Newtonian fluid. Building on the mean-field framewor…
Frozen Cheerios effect: Particle-particle interaction induced by an advancing solidification front
Jochem G. Meijer, Vincent Bertin, Detlef Lohse
Particles at liquid interfaces have the tendency to cluster due to capillary forces competing with gravitational buoyancy (i.e., normal to the distorted free surface). This is know…
Interfacial dripping faucet: generating monodisperse liquid lenses
Lorène Champougny, Vincent Bertin, Jacco H. Snoeijer +1
We present a surface analog to a dripping faucet, where a viscous liquid slides down an immiscible meniscus. Periodic pinch-off of the dripping filament is observed, generating a s…
Viscoelastic lubrication of a submerged cylinder sliding down an incline
Alexandros T. Oratis, Kai van den Berg, Vincent Bertin +1
Lubrication flows between two solid surfaces can be found in a variety of biological and engineering settings. In many of these systems, the lubricant exhibits viscoelastic propert…
