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 …

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 …

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 …

A combined experimental, numerical and theoretical investigation of the geometric scaling of
the onset of a purely elastic flow instability in serpentine channels is presented. Good …

The lid-driven cavity flow is a well-known benchmark problem for the validation of new
numerical methods and techniques. In experimental and numerical studies with 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 …

High-elasticity simulations of flows through a two-dimensional (2D) 4: 1 abrupt contraction
and a 4: 1 three-dimensional square–square abrupt contraction were performed with a finite …

We investigate the stability of steady planar stagnation flows of a dilute polyethylene oxide
(PEO) solution using T-shaped microchannels. The precise flow rate control and well …

This work presents a generic kernel-conformation tensor transformation for a large class of
differential constitutive models, in which several matrix kernel-transformation families can be …

Viscoelastic fluids are a subclass of complex fluids used in widespread applications ranging
from biological to large-scale industrial settings. These fluids are often associated with …
