Yield stress fluid flows: A review of experimental data

P Coussot - Journal of Non-Newtonian Fluid Mechanics, 2014 - Elsevier
Yield stress fluids are encountered in a wide range of applications: toothpastes, cements,
mortars, foams, muds, mayonnaise, etc. The fundamental character of these fluids is that …

Yielding to stress: recent developments in viscoplastic fluid mechanics

NJ Balmforth, IA Frigaard… - Annual review of fluid …, 2014 - annualreviews.org
The archetypal feature of a viscoplastic fluid is its yield stress: If the material is not sufficiently
stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows like …

Design of yield-stress fluids: A rheology-to-structure inverse problem

AZ Nelson, RH Ewoldt - Soft matter, 2017 - pubs.rsc.org
We present a paradigm for the design of yield-stress fluids, using six archetypal materials for
demonstration. By applying concepts of engineering design, we outline a materials design …

Significant involvement of double diffusion theories on viscoelastic fluid comprising variable thermophysical properties

M Sohail, U Nazir, O Bazighifan, RA El-Nabulsi… - Micromachines, 2021 - mdpi.com
This report examines the heat and mass transfer in three-dimensional second grade non-
Newtonian fluid in the presence of a variable magnetic field. Heat transfer is presented with …

Measuring the surface tension of yield stress fluids

J Boujlel, P Coussot - Soft Matter, 2013 - pubs.rsc.org
With the aim of studying the impact of capillary forces on the flow of yield stress fluids we
investigate the properties of a film formed by withdrawing a blade from a bath of such a …

[HTML][HTML] Extending yield-stress fluid paradigms

AZ Nelson, RE Bras, J Liu, RH Ewoldt - Journal of Rheology, 2018 - pubs.aip.org
We report experimental measurements of high extensibility of several yield-stress fluids,
demonstrating a behavior completely outside the standard paradigm of model materials and …

Lattice Boltzmann modeling for multiphase viscoplastic fluid flow

C Xie, J Zhang, V Bertola, M Wang - Journal of Non-Newtonian Fluid …, 2016 - Elsevier
We present a lattice Boltzmann model to simulate multiphase viscoplastic fluid flow. It is an
extended model based on the free-energy-based lattice Boltzmann method (LBM) for …

Viscoplastic water entry

M Jalaal, D Kemper, D Lohse - Journal of fluid mechanics, 2019 - cambridge.org
The impact of viscoplastic droplets on a free surface of water is studied. The droplet
undergoes an elasto-plastic deformation at the early stages of water entry. At large time, the …

Producing shape-engineered alginate particles using viscoplastic fluids

S Asadi, AZ Nelson, PS Doyle - Soft Matter, 2022 - pubs.rsc.org
Non-spherical hydrogel particles are of fundamental interest and can find use in a variety of
applications ranging from pharmaceuticals to biomedical to food. Here, we report a new …

Pinch-off dynamics in foams, emulsions and suspensions

FM Huisman, SR Friedman, P Taborek - Soft Matter, 2012 - pubs.rsc.org
The break up of a non-Newtonian yield stress fluid bridge (acrylic paint, mayonnaise, hair
gel, foam, and bentonite) was investigated. The minimum neck radius, hmin, was measured …
