From the Phan-Thien Tanner / Oldroyd-B non-Newtonian model to the double shear thining Rabinowisch thin film model
In this paper, an asymptotic expansion is used to derive a description of Phan-Tien Tanner / Oldroyd-B flows in the thin film situation without the classical “Upper Convective Maxwell” assumption. We begin with a short presentation of the Phan-Thien Tanner / Oldroyd-B models which introduce viscoelastic effects in a solute-solvant mixture. The three dimensional flow is described using five para...

A Model for Film-forming with Newtonian and Shear Thinning Fluids
The formation of a thin film by (i) the slow penetration of a gas bubble into a liquid filled tube, (ii) the withdrawal of a planar substrate from a liquid filled gap, is investigated theoretically for the cases of both Newtonian and shear thinning liquids; the latter conforming to either a power law or Ellis model. Formulated as a boundary value problem underpinned by lubrication theory, the a...
