A shear and elongational decomposition approach of the rate-of-deformation tensor for non-Newtonian flows with mixed kinematics

PJ Oliveira - Journal of Fluid Mechanics, 2024 - cambridge.org
We propose a novel approach for non-Newtonian viscoelastic steady flows based on a
decomposition of the rate-of-deformation tensor which here, in a simplified version, leads to …

Multiscale SPH simulations of viscoelastic injection molding processes based on bead-spring chain model

X Xu, L Tian, P Yu - Engineering Analysis with Boundary Elements, 2023 - Elsevier
In this paper we present an extension of a multiscale smoothed particle hydrodynamics
(SPH) method to transient viscoelastic injection molding processes. Specifically, we use the …

Viscoelastic fluid flow in a slowly varying planar contraction: the role of finite extensibility on the pressure drop

B Mahapatra, T Ruangkriengsin, HA Stone… - arXiv preprint arXiv …, 2024 - arxiv.org
We analyze the steady viscoelastic fluid flow in slowly varying contracting channels of
arbitrary shape and present a theory based on the lubrication approximation for calculating …

On the similarities of the sPTT and FENE-P models for polymeric fluids

M Davoodi, K Zografos, RJ Poole - Science Talks, 2022 - pureportal.strath.ac.uk
For many commonly used single mode viscoelastic constitutive equations of differential type,
it is well known that they share many features. For example, in certain parameter limits the …
