    • Capillary Break-up Rheometry of Low-Viscosity Elastic Fluids 

      Rodd, Lucy E.; Scott, Timothy P.; Cooper-White, Justin J.; McKinley, Gareth H. (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 

      Stocker, Roman; Hosoi, A.E. (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 ...

    • The Inertio-Elastic Planar Entry Flow of Low-Viscosity Elastic Fluids in Micro-fabricated Geometries 

      Rodd, Lucy E.; Scott, Timothy P.; Boger, David V.; Cooper-White, Justin J.; McKinley, Gareth H. (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 ...

    • Peeling, healing and bursting in a lubricated elastic sheet 

      Hosoi, A.E.; Mahadevan, L. (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 ...
