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-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 ...

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.

Shear thickening in colloidal dispersions
AIP Conference Proceedings, 1999We present a simplified model of shear thickening in concentrated colloids. The key idea of the model is that the trajectories of close approaching particles be simultaneously consistent with both the stress and the shear rate of the suspension. The weak shear thickening of Brownian hard spheres is reproduced.

Onset of shear thickening in a simple fluid
The European Physical Journal E, 2004We report on nonequilibrium molecular-dynamics simulations of the shear-thickening transition in a simple fluid under shear. We relate the shear-thickening transition to the onset of instabilities in the flow profile and to that of dramatic variations in normal stress differences.

Origins of shear dilatancy and shear thickening phenomena
Chemical Physics Letters, 1984Abstract Volumetric and rheological dilatancy (shear thickening) are shown by molecular dynamics calculations to occur in simple classical dense fluids in both two and three dimensions. These phenomena, commonly associated with colloidal suspensions, are kinetic manifestations of the transition to athermal particle dynamics at shear rates approaching
