The literature on thixotropy modeling is reviewed, with particular emphasis on models for
yield stress materials that possess elasticity. The various possible approaches that have …

Abstract Generalised Newtonian Fluid (GNF) models which assume that the viscosity of a
non-Newtonian fluid can be modelled inelastically as a time-independent, ie instantaneous …

Slot coating is a common method in the manufacture of a wide variety of products. It belongs
to a class of coating method known as premetered coating: the thickness of the coated liquid …

Material extrusion is an additive manufacturing process in which material is selectively
dispensed through a nozzle. In this work, we are focused on fused filament fabrication (FFF) …

Creating an entry vortex growth simulation to show viscous and elastic fluid behaviors has
always been a major challenge for the computational rheology of well-characterized …

The region of acceptable quality in the space of operating parameters of a coating process is
usually bounded by various coating defects. An important limit of the slot coating process is …

Abrupt contraction flows involving viscoelastic fluids represent a longstanding computational
challenge within the field of non-Newtonian fluid mechanics. Despite the apparent simplicity …

Polymer rheology profoundly influences the intricate dynamics of material extrusion in fused
filament fabrication (FFF). This numerical study, which uses the Giesekus model fed with a …

Astarita [J. Non-Newton Fluid Mech. 6 (1979) 69–76] proposed a local and objective
criterion to classify flows. His criterion is not restricted to motions with constant relative …

The flow of a viscoelastic fluid through a microfluidic flow-focusing device is investigated
numerically with a finite-volume code using the upper-convected Maxwell (UCM) and Phan …
