Nanobubble-induced flow of immersed glassy polymer films
Christian Pedersen, Shuai Ren, Yuliang Wang +2
We study the free-surface deformation dynamics of an immersed glassy thin polymer film supported on a substrate, induced by an air nanobubble at the free surface.We combine analyti…
Universal Self-Similar Attractor in the Bending-Driven Leveling of Thin Viscous Films
Christian Pedersen, Thomas Salez, Andreas Carlson
We study theoretically and numerically the bending-driven leveling of thin viscous films within the lubrication approximation. We derive the Green's function of the linearized thin…
Film coating by directional droplet spreading on fibers
Tak Shing Chan, Carmen L. Lee, Christian Pedersen +2
Plants and insects use slender conical structures to transport and collect small droplets, which are propelled along the conical structures due to capillary action. These droplets…
Film deposition of a self-propelled droplet on a cone with slip
T. S. Chan, C. Pedersen, J. Koplik +1
We study the dynamic wetting of a self-propelled viscous droplet using the time-dependent lubrication equation on a conical-shaped substrate for different cone radii, cone angles a…
Soft nanobubbles can deform rigid glasses
Shuai Ren, Christian Pedersen, Andreas Carlson +2
Confined glasses and their anomalous interfacial rheology raise important questions in fundamental research and numerous practical applications. In this Letter, we study the influe…
Asymptotic regimes in elastohydrodynamic and stochastic leveling on a viscous film
Christian Pedersen, John Niven, Thomas Salez +2
An elastic sheet that deforms near a solid substrate in a viscous fluid is a situation relevant to various dynamical processes in biology, geophysics and engineering. Here, we stud…
