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 Worthington jets & droplets produced by bursting bubbles
Ayush K. Dixit, Alexandros Oratis, Konstantinos Zinelis +2
Bubble bursting and subsequent collapse of the open cavity at free surfaces of contaminated liquids can generate aerosol droplets, facilitating pathogen transport. After film ruptu…
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…
