Rates of shear in coaxial cylinder viscometers
Rheologica Acta, 1973A common geometry used in rotational viscometry consists of two concentric cylinders in which the test fluid is sheared in the annulus between the cylinders. In this type of instrument the calculation of the shear stress from the measured torque is straightforward but the determination of the corresponding rate of shear is a difficult problem unless ...

Shear Rate in the Couette Viscometer
Transactions of the Society of Rheology, 1968The problem of determining the shear rate in a non-Newtonian fluid sheared between rotating coaxial cylinders has eluded exact solution, although many approximations and solutions in infinite series form are available. The present paper shows that certain of the infinite series which appear in Krieger and Elrod’s solution [J. Appl. Phys., 24, 134 (1953)

Shear-Rate Nonanalyticity in Simple Liquids
Journal of Non-Equilibrium Thermodynamics, 1987A non-equilibrium thermodynamic theory of shear relaxation in a small subvolume of a simple liquid introduces the volume, temperature, particle number, traceless elastic shearing strain \(\sigma^{\dag}_{ij}\), and the volume fraction \(\zeta\), of locally-dilated spherical regions as internal state variables.

Effect of shear rate on microstructure and rheological properties of sheared wheat doughs
Journal of Cereal Science, 2008Abstract Structure formation in dough systems is the result of an interplay between processing conditions and subsequent interactions in the protein phase. These interactions can be both of a covalent (disulfide bonds) and physical nature and occur at all length scales.

Formulation of shear rate sensitive multiple emulsions
Journal of Controlled Release, 2001This work mainly concentrates on the formulation of W/O/W multiple emulsions capable of breaking and releasing their inner aqueous phase under shear rates compatible with agroalimentary, pharmaceutical and cosmetic applications. Three kinds of multiple emulsions were studied: one with a high concentration of primary emulsion, not viscosified in the ...

Artificial Organs, 1989
Abstract: The hydrodynamic effect of periodically fluctuating shear rate on erythrocyte destruction was quantitatively studied in vitro in comparison with constant shear rates. Uniform shear rates (< 1,000 s‐1; constant or sinu‐soidally fluctuating with time) were applied to heparin‐ized canine blood contained in the concavo‐convex type of Couette ...

Study of the Effect of Shear Rates on Residual Shear of Landslide Soil
Advanced Materials Research, 2013The residual strength is one of the most important strength parameters to evaluate the stability of a reactivated landslide slope, but the relation between residual strength gained by using ring shear tests and shear speed still remains unclear. In order to clarify the relationship between them, the variation in residual friction coefficient of slip ...
