Complex fluids exist in nature and are continually engineered for specific applications
involving the addition of macromolecules to a solvent, among other means. This imparts …

The objective of this article is to summarise the work that we have been doing as a group in
the context of stabilised finite element formulations for viscoelastic fluid flows. Viscoelastic …

In this work we implement the log-conformation reformulation for viscoelastic constitutive
equations as proposed by Fattal and Kupferman (2004) in the open-source CFD-software …

Ensuring a high degree of dimensional accuracy of the printed part is critical in the
development of additive manufacturing techniques. The advent of computational tools to …

Abstract An arbitrary Lagrangian Eulerian finite element method based numerical code for
viscoelastic fluids using well-known stabilization techniques (SUPG, DEVSS, log …

The dynamics of a cell suspended in a Newtonian liquid subjected to a pressure-driven flow
at non-negligible inertia in cylindrical and square cross section microfluidic channels is …

Viscoelastic fluids are highly challenging from the rheological standpoint, and their
discretization demands robust, efficient numerical solvers. Simulating viscoelastic flows …

A 3D transient non-isothermal finite element code is developed to predict the extrudate
shape of viscoelastic fluids emerging from an asymmetric keyhole shaped die. The corner …

In this paper we propose a novel approach to solve the inverse problem of three-
dimensional die design for extrudate swell, using a real-time active control scheme. To this …

Rigid particles suspended in viscoelastic fluids under shear can align in string-like structures
in the flow direction. Although this phenomenon was first reported almost four decades ago …
