Shear Thinning and Orientational Ordering of Wormlike Micelles

Physical Review Letters, 2005
Shear thinning and orientation of cylindrical surfactant and block copolymer micelles was investigated by rheo-SANS (small-angle neutron scattering) experiments. Shear thinning and orientation occur for shear rates (.)gamma tau(dis)>>1, where tau(dis) is the disentanglement time of the micelles.

Shear thinning of colloidal dispersions

Journal of Rheology, 1998
In this paper we calculate numerically the shear induced distortion of the equilibrium microstructure in a dilute colloidal suspension. In the low density limit, our predictions both with and without hydrodynamic interactions follow the form of the Ree–Eyring equation for the shear rate dependence of the rheology.

Mesoscale modeling of shear-thinning polymer solutions

The Journal of Chemical Physics, 2014
We simulate the linear and nonlinear rheology of two different viscoelastic polymer solutions, a polyisobutylene solution in pristane and an aqueous solution of hydroxypropylcellulose, using a highly coarse-grained approach known as Responsive Particle Dynamics (RaPiD) model.

Shear-Thinning and Dilatant Rheologies

1994
The rheological properties of crowded suspensions and pastes of powders dispersed in liquids is of fundamental importance to the forming properties of any ceramic article formed by the wet process. This includes such diverse products as brick and tile, whitewares, many refractories, electronic ceramics, and high performance ceramics.

A Modification of Murray's Law for Shear-Thinning Rheology

Journal of Biomechanical Engineering, 2015
This study reformulates Murray's well-known principle of minimum work as applied to the cardiovascular system to include the effects of the shear-thinning rheology of blood. The viscous behavior is described using the extended modified power law (EMPL), which is a time-independent, but shear-thinning rheological constitutive equation.

Shear thinning in concentrated dispersions

Journal of Physics: Condensed Matter, 1996
A theory is presented to predict the effective shear viscosity of concentrated dispersions in steady state shear flow as a function of the volume fraction, particle size, interparticle interactions, and shear rate. Shear thinning has been qualitatively argued to be a result of shear-induced change in microstructure, which we shall discuss in terms of ...

Nonlinear Electrophoresis of Microparticles in Shear Thinning Fluids

Langmuir
The nonlinear electric field dependence of particle electrophoresis has been demonstrated to occur in Newtonian fluids for highly charged particles under large electric fields. It has also been predicted to arise from the rheological effects of non-Newtonian fluids even at small electric fields.

Shear-thinning drop formation

2003
A volume-of-fluid numerical method is used to predict the dynamics of drop formation from a nozzle with a circular exit, directed vertically downwards in air, when the drop fluid is shear-thinning. The validity of the numerical calculation is first confirmed for a Newtonian fluid by comparison with experimental measurements.
