INTRODUCTION Simulation of constant-viscosity memory-fluids flows is undertaken, considering single-mode differential models and two different numerical schemes. Comparisons are performed against experimental observations, for pressure drop (∆P) and vortex cell-size (X). We interpret such issues through increasing flow-rate for a given fluid. Tests have(More)
This study investigates the numerical solution of viscoelastic flows using two contrasting high-order finite volume schemes. We extend our earlier work for Poiseuille flow in a planar channel and a Single Extended Pom-Pom (SXPP) model [1], to determine steady-state solutions for planar 4:1 sharp contraction flows. The numerical techniques employed are(More)

We extend our earlier work for Poiseuille flow in a planar channel and the single equation form of the extended pom-pom (SXPP) model [1], to determine steady-state solutions for planar 4:1 sharp contraction flows. The numerical(More)
