Shear-Rate-Independent Diffusion in Granular Flows.
Physical Review Letters, 2015We computationally study the behavior of the diffusion coefficient D in granular flows of monodisperse and bidisperse particles spanning regions of relatively high and low shear rate in open and closed laterally confined heaps.

Shear and objective stress rates in hypoplasticity
International Journal for Numerical and Analytical Methods in Geomechanics, 2003AbstractThis paper addresses some questions referring to shear within the context of hypoplasticity and the importance of objective stress rates in constitutive modelling. A short introduction to the stress changes due to rotations is followed by a discussion of the merits of the individual objective stress rates.

Thrombus Formation at High Shear Rates
Annual Review of Biomedical Engineering, 2017The final common pathway in myocardial infarction and ischemic stroke is occlusion of blood flow from a thrombus forming under high shear rates in arteries. A high-shear thrombus forms rapidly and is distinct from the slow formation of coagulation that occurs in stagnant blood.

Effects of Shear Rate and Protein Concentration on Amyloidogenesis via Interfacial Shear
The Journal of Physical Chemistry B, 2021The influence of hydrodynamics on protein fibrillization kinetics is relevant to biophysics, biochemical reactors, medicine, and disease. This investigation focused on the effects of interfacial shear on the fibrillization kinetics of insulin. Human insulin served as a model protein for studying shear-induced fibrillization with relevance to amyloid ...

A Jet Viscometer with Variable Rate of Shear
Review of Scientific Instruments, 1946A viscometer consisting of a glass jet which is inserted in a closed system is described. With this instrument high rates of shear of the order of magnitude of 100,000 sec.−1 can be reached for hydraulic oils. Observations on straight mineral oils of sufficiently high viscosity to exclude turbulence, on refined rape oil, and on castor oil, showed that ...

Effect of shear rate on the rate of polymerization of styrene
Polymer, 1983Abstract Application of shear was found to have considerable effect on the radical polymerization of styrene initiated by benzoyl peroxide. The initial rate of polymerization decreases by as much as 30% for low shear rates (γ), but on further increasing γ it increases slightly, levelling ultimately at the 10% reduction level.

Effect of shear rate on activation rate of factor X
Annals of Biomedical Engineering, 1978The activation rates of Factor X in the intrinsic coagulation pathway and by RVV were measured in the stationary condition in a concentric cylinder device in a shear field and in a capillary flow reactor. The shear rates in the cylinder device were 70 and 140 sec−1 and the range of the flow rate in the flow reactor was from 0.59 to 1.20 cm3/min.

Rubber Plastimeter with Uniform Rate of Shear - Shearing-Cone Plastimeter
Journal of Scientific Instruments, 1945Abstract A new shearing-cone plastometer, suitable for investigating the plastic-flow relations of highly viscous materials over a wide range of stress, is described. A mushroom-shaped rotor, having upper and lower surfaces of conical type, is rotated in the plastic material contained in a cylindrical mould.

Effects of shear rate on rouleau formation in simple shear flow
Biorheology, 1988A kinetic equation for rouleau formation in a simple shear flow is derived, based on several assumptions. These are (a) colliding rouleaux stick to one another with a certain probability to form a single rouleau; (b) simultaneous collisions between more than two rouleaux are negligible; (c) rouleaux are broken by a viscous force exerted by the ...

On the Rate of Shear in Capillary Tubes
Journal of Rheology, 1930Since little is known concerning the laws of plastic flow, it is often convenient to use approximate methods of calculation based on the law of Poiseuille for simple viscous liquids. Neglecting the kinetic energy correction, the reciprocal of the viscosity is Fluidity = 4qπR3PR2L = YX (1) where q = rate of flow in cm3 per second
