Capillary-Stress Controlled Rheometer Reveals the Dual Rheology of Shear-Thickening Suspensions

Physical Review X, 2023
The rheology of dense colloidal suspensions, which may undergo discontinuous shear thickening or shear jamming, is particularly difficult to analyze with conventional rheometers.

Order and density fluctuations near the boundary in sheared dense suspensions

Frontiers in Physics, 2022
We introduce a novel approach to reveal ordering fluctuations in sheared dense suspensions, using line scanning in a combined rheometer and laser scanning confocal microscope. We validate the technique with a moderately dense suspension, observing modest

Turning a yield-stress calcite suspension into a shear-thickening one by tuning inter-particle friction

, 2020
We show that a suspension of non-Brownian calcite particles in glycerol-water mixtures can be tuned continuously from being a yield-stress suspension to a shear-thickening suspension without a measurable yield stress by the addition of various ...

Discontinuous Shear Thickening in Cornstarch Suspensions

EPJ Web of Conferences, 2017
We study the emergence of discontinuous shear-thickening (DST) in cornstarch, the well know system for this phenomenon, by combining macroscopic rheometry with local Magnetic Resonance Imaging (MRI) measurements. We bring evidence that macroscopic DST is

Microstructure and thickening of dense suspensions under extensional and shear flows

, 2017
Dense suspensions are non-Newtonian fluids that exhibit strong shear thickening and normal stress differences. Using numerical simulation of extensional and shear flows, we investigate how rheological properties are determined by the microstructure that ...

Shear thinning and thickening of cemented paste backfill

Applied Rheology, 2019
Cemented paste backfill (CPB) is considered to be a concentrated suspension in which tailings are bonded together by the hydraulic binder and water, and it has a high solid volume concentration (≥50 vol.%).

Fluctuations and like-torque clusters at the onset of the discontinuous shear thickening transition in granular materials

Communications Physics, 2021
An open question in the field of granular materials and non-equilibrium physics is the origin and interpretation of frictional effects and spatiotemporal fluctuation in the discontinuous shear thickening transition.
