Effects of shear rate on rouleau formation in simple shear flow

Biorheology, 1988
A 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 ...

Simple shear tests with a varying shearing direction during cyclic shearing

Géotechnique Letters, 2014
Tests with cyclic lateral loading on a pile have shown that the pile reacts to a change of loading direction with increasing accumulation of lateral displacements. This phenomenon is known as ‘pile drift’. To investigate this behaviour at small scale under laboratory conditions, a specifically designed simple shear apparatus with two shearing axes was

Hemolysis in simple shear flows

AIChE Journal, 1970
AbstractWhole human blood was sheared in the flow field of a concentric cylinder Couette viscometer in the hope of isolating the physical traumas specifically related to the escape of intracellular hemoglobin. The experimental results indicated that laminar shear stresses per se were not instrumental within the investigated range (up to 600 dynes/sq.cm.

Shear-Rate Nonanalyticity in Simple Liquids

Journal of Non-Equilibrium Thermodynamics, 1987
A 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.

Spatial Simple Waves on a Shear Flow

Journal of Applied Mechanics and Technical Physics, 2002
The paper studies simple waves of the shallow-water equations describing three-dimensional wave motions of a rotational liquid in a free-boundary layer. Simple wave equations are derived for the general case. The existence of unsteady or steady simple waves adjacent continuously to a given steady shear flow along a characteristic surface is proved ...

Onset of shear thickening in a simple fluid

The European Physical Journal E, 2004
We 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.

Design of Members for Shear and Simple Shear Connections

International Journal of Science, Strategic Management and Technology
This study focuses on the design of members for shear and simple shear connections in steel structures to ensure safe load transfer and structural stability. The purpose is to evaluate connection behavior and identify critical design parameters. The methodology includes analytical design based on standard codes and comparison of different connection ...

Simple polarization shearing interferometry for a microscope

Applied Optics, 1988
A new and simple way for a microscope to make an interferogram is proposed and demonstrated. This method is based on the polarization interferometry of the changing polarizability of light by a half-mirror using a laser as the light source. It is convenient to use a microscope to observe concentration gradients and phase objects, such as studies of ...

The anisotropy of simple shearing flow

Rheologica Acta, 1973
The optical analogue of the second normal stress difference, namely,n 22 –n 33 has been measured for several polymer systems. The experimental method is direct and makes use of capillary and slit dies. For the polymer melts examined — ranging from a polystyrene with a viscosity of 104 Ns/m2 to a PIB of viscosity 50 Ns/m2 — a non-zero (n 22 –n 33) was ...

Flows Close to Simple Shear and Simple Extension

1994
Several complex problems of viscoelastic fluid mechanics, of both scientific and industrial importance, are gathered in this chapter. Special attention is paid to easily estimating their solution and to revealing the properties of the constitutive equations responsible for the occurrence of new effects.
