Structure-property relationship of a soft colloidal glass in simple and mixed flows
Hypothesis Under specific conditions, rod-like cellulose nanocrystals (CNC) can assemble
into structurally ordered soft glasses (SGs) with anisotropy that can be controlled by applying …

The concept of elasto-visco-plasticity and its application to a bubble rising in yield stress fluids
Based on the original ideas by Oldroyd in 1947, Saramito in 2007 introduced a generally
acceptable model for yield stress fluids that also accounts for their elasticity. We use this …

Hydrodynamic interaction between coaxially rising bubbles in elastoviscoplastic materials: Equal bubbles
We consider the buoyancy-driven rise and interaction between two coaxially placed bubbles
of equal size and constant volume that are initially stationary inside an elastoviscoplastic …

A revisitation of White− Metzner viscoelastic fluids
HC Tseng - Physics of Fluids, 2021 - pubs.aip.org
The famous White–Metzner (WM) constitutive equation expresses a relatively simple
nonlinear viscoelastic fluid of polymer melts. However, such a differential stress model …
