How elasticity affects bubble pinch-off
Coen I. Verschuur, Alexandros T. Oratis, Vatsal Sanjay +1
The pinch-off of bubbles in viscoelastic liquids is a fundamental process that has received little attention compared to viscoelastic drop pinch-off. While these processes exhibit…
Diffusion from particle-coated drops: the subtle role of particle size
Alexandros T. Oratis, Matteo Camagna, Timo J. J. M. van Overveld +1
Many natural and industrial systems involve particle-laden interfaces. Because interfacial particles prevent the coalescence and coarsening of drops, they hold promise for various…
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…
Sticking without contact: Elastohydrodynamic adhesion
Vincent Bertin, Alexandros T. Oratis, Jacco H. Snoeijer
The adhesion between dry solid surfaces is typically governed by contact forces, involving surface forces and elasticity. For surfaces immersed in a fluid, out-of-contact adhesion…
