Peeling, healing and bursting in a lubricated elastic sheet
(PRL, 2004)
We consider the dynamics of an elastic sheet lubricated by the flow of a thin layer of fluid that separates it from a rigid wall. By considering long wavelength deformations of the sheet, we derive an evolution equation ...
The Inertio-Elastic Planar Entry Flow of Low-Viscosity Elastic Fluids in Micro-fabricated Geometries
(2004-12-17)
The non-Newtonian flow of dilute aqueous polyethylene oxide (PEO) solutions through
microfabricated planar abrupt contraction-expansions is investigated. The contraction
geometries are fabricated from a high-resolution ...
Capillary Break-up Rheometry of Low-Viscosity Elastic Fluids
(2004-11-01)
We investigate the dynamics of the capillary thinning and break-up process for low viscosity
elastic fluids such as dilute polymer solutions. Standard measurements of the evolution of the
midpoint diameter of the necking ...
Corner Flows in Free Liquid Films
(2004-08-24)
A lubrication-flow model for a free film in a corner is presented. The model, written in the hyperbolic coordinate system ξ = x² – y², η = 2xy, applies to films that are thin in the η direction. The lubrication approximation ...
