Dense non-Brownian suspension has rich rheology and is hard to understand, especially for distinguishing continuous shear thickening (CST) from discontinuous shear thickening (DST). By studying the shear stress dependent rheology of a well-known DST suspension of cornstarch in water, we find that the transition from CST to DST could occur not only by ...

From shear thickening to shear-induced jamming
Physical Review E, 2002We show that applying shear to a suspension may lead to either thickening or permanent jamming, depending on the volume fraction of the considered suspension. Interpreting measurements of conductivity under shear, we invoke a dynamical structural transition to explain the origin of shear thickening in suspensions of non-Brownian particles.

Shear thickening-shear thinning and shear thinning-shear thickening transitions in polymeric systems
Caderno PedagógicoThis review explores the complex rheological behaviors of hydrogels, specifically focusing on shear thinning-shear thickening (PD) and the less common shear thickening-shear thinning (DP) transitions. While shear thinning (viscosity decrease with increasing shear rate) is widely utilized in applications like 3D printing and injectables, and shear ...

Abstract Concentrated slurry is known to exhibit shear thickening behavior, in which viscosity increases as the shear rate ascends. However, to identify the differences between this shear thickening behavior and rapid increases in viscosity (such as the dilatancy behavior of starch, sand, and other concentrated slurries) and the smooth increases in ...

Shear Thickening and Turbulence in Simple Fluids
Physical Review Letters, 1986In 1984 Erpenbeck observed a shear-induced alignment of particles into strings in nonequilibrium molecular-dynamics simulations of shear flow in the hard-sphere fluid. In this paper we show that this effect arises from the use of a thermostat which assumes a stable linear velocity profile.

Shear thickening in a model colloidal suspension
The Journal of Chemical Physics, 2005We study the rheology of model colloidal suspensions using molecular-dynamics simulations. We relate the onset of shear thickening to the transition from a low-viscosity regime, in which the solvent facilitates the flow of colloids, to a high-viscosity regime associated with jamming of the colloids and the formation of chains of colloids.

Shear-thickening in aqueous surfactant-associative thickener mixtures
Journal of Coatings Technology and Research, 2011Associative thickeners represent an important class of rheology modifiers used in waterborne coatings. Understanding molecular level interactions between associative thickeners and surfactants has been the subject of a number of prior studies. Our recent studies focused on the behavior of a hydrophobically modified, aminoplast ether (HEAT) associative ...

Optimal Control of Shear-Thickening Flows
SIAM Journal on Control and Optimization, 2013We study optimal control problems of systems describing the flow of incompressible shear-thickening fluids. We prove existence of solutions and derive necessary optimality conditions under precise restrictions on the optimal control.
