Rheology of suspensions of non-Brownian soft spheres across the jamming and viscous-to-inertial transitions

F Tapia, CW Hong, P Aussillous, É Guazzelli - Physical Review Letters, 2024 - APS
The rheology of suspensions of non-Brownian soft spheres is studied across jamming but
also across the viscous and inertial regimes using a custom pressure-and volume-imposed …

Rheology of dense granular suspensions across flow regimes

É Guazzelli - Physical Review Fluids, 2024 - APS
Dense granular suspensions, which consist of concentrated mixtures of non-Brownian
particles suspended in a liquid, are ubiquitous in many natural phenomena (eg, landslides …

Diverging viscosity and soft granular rheology in non-Brownian suspensions

T Kawasaki, D Coslovich, A Ikeda, L Berthier - Physical Review E, 2015 - APS
We use large scale computer simulations and finite-size scaling analysis to study the shear
rheology of dense three-dimensional suspensions of frictionless non-Brownian particles in …

Unified theory of inertial granular flows and non-Brownian suspensions

E DeGiuli, G Düring, E Lerner, M Wyart - Physical Review E, 2015 - APS
Rheological properties of dense flows of hard particles are singular as one approaches the
jamming threshold where flow ceases both for aerial granular flows dominated by inertia …

Unifying suspension and granular rheology

F Boyer, É Guazzelli, O Pouliquen - Physical review letters, 2011 - APS
Using an original pressure-imposed shear cell, we study the rheology of dense
suspensions. We show that they exhibit a viscoplastic behavior similarly to granular media …

Bridging the rheology of granular flows in three regimes

S Chialvo, J Sun, S Sundaresan - … Review E—Statistical, Nonlinear, and Soft …, 2012 - APS
We investigate the rheology of granular materials via molecular dynamics simulations of
homogeneous, simple shear flows of soft, frictional, noncohesive spheres. In agreement with …

Viscous to inertial transition in dense granular suspension

F Tapia, M Ichihara, O Pouliquen, É Guazzelli - Physical Review Letters, 2022 - APS
Granular suspensions present a transition from a Newtonian rheology in the Stokes limit to a
Bagnoldian rheology when inertia is increased. A custom rheometer that can be run in a …

Towards a unified description of the rheology of hard-particle suspensions

BM Guy, M Hermes, WCK Poon - Physical review letters, 2015 - APS
The rheology of suspensions of Brownian, or colloidal, particles (diameter d≲ 1 μ m) differs
markedly from that of larger grains (d≳ 50 μ m). Each of these two regimes has been …

Viscous forces and bulk viscoelasticity near jamming

K Baumgarten, BP Tighe - Soft Matter, 2017 - pubs.rsc.org
When weakly jammed packings of soft, viscous, non-Brownian spheres are probed
mechanically, they respond with a complex admixture of elastic and viscous effects. While …

Unifying suspension and granular flows near jamming

E DeGiuli, M Wyart - EPJ Web of Conferences, 2017 - epj-conferences.org
Rheological properties of dense flows of hard particles are singular as one approaches the
jamming threshold where flow ceases, both for granular flows dominated by inertia, and for …
