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)

Although the development of rheological software has kept pace with the advances in modern rheometrical instruments the process of data analysis and interpretation remains fallible and can be prone to some signiicant errors. The reason for this is that the ability and knowledge of human beings to utilise the intruments and data at their disposal can be… (More)

The relaxation spectrum is an important tool for studying the behaviour of viscoelastic materials. The most popular procedure is to use data from a small-amplitude oscillatory shear experiment to determine the parameters in a multi-mode Maxwell model. However, the discrete relaxation times appear nonlinearly in the mathematical model for the relaxation… (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 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)
