Shear-thickening fluids in biologically relevant agents. [PDF]
Biorheology, 2019 BACKGROUND: The rheology of shear thickening fluids is well characterized for many physical applications, however the literature surrounding biologically or cryobiologically compatible shear thickening fluids is less well understood. OBJECTIVE: This study examined fluids consisting of corn-derived hydroxyethyl starch with a variety of sugars and ...

Physical Review Fluids, 2017 A cornstarch suspension is the quintessential particulate system that exhibits shear thickening. By adding large non-Brownian spheres to a cornstarch suspension, we show that shear thickening can be significantly enhanced. More precisely, the shear-thickening transition is found to be increasingly shifted to lower critical shear rates.

Shear fronts in shear-thickening suspensions [PDF]
Physical Review Fluids, 2018 Snapshot of a propagating shear front that transforms a dense suspension from a fluid into a jammed, solid-like state. A comprehensive description of this transformation is developed, which links the transient dynamics to parameters obtainable from steady-state rheology.

Shear-thinning and shear-thickening emulsions in shear flows [PDF]
Physics of Fluids, 2021 We study the rheology of a two-fluid emulsion in semiconcentrated conditions; the solute is Newtonian while the solvent is an inelastic power-law fluid. The problem at hand is tackled by means of direct numerical simulations using the volume of fluid method.

Shear Thickening and Migration in Granular Suspensions [PDF]
Physical Review Letters, 2010 We study the emergence of shear thickening in dense suspensions of non-Brownian particles. We combine local velocity and concentration measurements using Magnetic Resonance Imaging with macroscopic rheometry experiments. In steady state, we observe that the material is heterogeneous, and we find that that the local rheology presents a continuous ...

Shear-Thickening Composites for On-Demand Rebound Performance and Softness
Inventions, 2020 For footwear insoles, high rebound performance is required in some instances such as for running, while softness for comfort is of higher importance during normal walking and standing to minimize high stress.

‘Shear thickening’ in non-shear flows: the effect of microstructure [PDF]
Journal of Fluid Mechanics, 2017 The bizarre behaviour of a cornstarch suspension (sometimes called oobleck) is well known to all of us who have led public engagement events. At the right solids fraction, it flows smoothly at slow speeds, but can be shattered with a quick spoon movement; if you prepare a large enough sample, you can run across the surface (but if you stand still, you ...

Synthesis and rheological performance of shear-thickening waterborne polyurethane
Materials Research ExpressShear-thickening fluids (STFs) are a new type of intelligent material with excellent performance whose viscosity increase sharply with the increase of shear rate or shear stress.

Shear thickening (dilatancy) in concentrated dispersions [PDF]
AIChE Journal, 1990 AbstractA new criterion is introduced for the onset of shear thickening in a concentrated dispersion. The criterion follows from the assumption that shear thickening occurs when the shear forces overrule the interparticle forces. A force balance at small interparticle distances is used to predict the dependence of this critical shear rate on the volume
