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 …

Polymeric materials display distinguished characteristics which stem from the interplay of
phenomena at various length and time scales. Further development of polymer systems …

In this work, we modify the viscoelastic solver available in the OpenFOAM® toolbox (Favero
et al., 2010), in order to improve its stability for differential-type constitutive equations. The …

Abrasive flow machining (AFM) is a surface finishing process for internal channels and
freeform surfaces that is based on the extrusion of an abrasive-laden viscoelastic media …

We propose an adaptive numerical solver for the study of viscoelastic 2D two-phase flows
using the volume-of-fluid method. The scheme uses the robust log conformation tensor …

We report a numerical study on the mixed electroosmotic and pressure-driven transport of
an Oldroyd-B fluid through a microchannel having high surface charge modulated walls. We …

We present an Eulerian free-surface flow solver for incompressible pseudoplastic and
viscoelastic non-Newtonian fluids. The free-surface flow solver is based on the …

A finite-volume based conservative level-set method is presented to numerically solve the
non-Newtonian multiphase flow problems. One set of governing equations is written for the …

This paper numerically investigates the mixing characteristics of an Oldroyd-B fluid flowing
through a micro-channel having discrete electrodes along its walls driven by both …

We present a comprehensive three-dimensional numerical investigation of the von Kármán
swirling flow between two parallel plates using the Oldroyd-B model and characterize the …
