Laminar axisymmetric flow of a weakly compressible viscoelastic fluid
(2012)The combined effects of weak compressibility and viscoelasticity in steady, isothermal, laminar axisymmetric Poiseuille flow are investigated. Viscoelasticity is taken into account by employing the Oldroyd-B constitutive ...

Perturbation solution of Poiseuille flow of a weakly compressible Oldroyd-B fluid
(2011)The isothermal, planar Poiseuille flow of a weakly compressible Oldroyd-B fluid is considered under the assumption that the density of the fluid obeys a linear equation of state. A perturbation analysis for all the primary ...

A timestepper approach for the systematic bifurcation and stability analysis of polymer extrusion dynamics
(2008)We discuss how matrix-free/timestepper algorithms can efficiently be used with dynamic non-Newtonian fluid mechanics simulators in performing systematic stability/bifurcation analysis. The timestepper approach to bifurcation ...
