Perspectives on shear banding in complex fluids

PD Olmsted - Rheologica Acta, 2008‏ - Springer
In this review, I present an idiosyncratic view of the current state of shear banding in complex
fluids. Particular attention is paid to some of the outstanding issues and questions facing the …

Shear bands in matter with granularity

P Schall, M Van Hecke - Annual Review of Fluid Mechanics, 2010‏ - annualreviews.org
Shear bands, localized regions where shear flows concentrate, form in many complex fluids
under a wide range of circumstances. In this review, we outline the main mechanisms that …

Rheology of giant micelles

ME Cates, SM Fielding - Advances in Physics, 2006‏ - Taylor & Francis
Giant micelles are elongated, polymer-like objects created by the self-assembly of
amphiphilic molecules (such as detergents) in solution. Giant micelles are typically flexible …

Complex dynamics of shear banded flows

SM Fielding - Soft Matter, 2007‏ - pubs.rsc.org
Many complex fluids undergo a flow induced transition to a state of coexisting bands of
differing viscosities and internal structuring. This effect, which is called “shear banding”, is …

Kinetics and mechanism of shear banding in an entangled micellar solution

YT Hu, A Lips - Journal of Rheology, 2005‏ - pubs.aip.org
We have studied shear banding in Couette flow using a combination of particle tracking
velocimetry (PTV), small angle light scattering, microscopic visualization, and flow …

Nonlinear shear and extensional flow dynamics of wormlike surfactant solutions

B Yesilata, C Clasen, GH McKinley - Journal of non-newtonian fluid …, 2006‏ - Elsevier
Nonlinear shear and extensional flow dynamics of a wormlike micellar solution based on
erucyl bis (2-hydroxyethyl) methyl ammonium chloride (EHAC) are reported here. The …

Gradient and vorticity banding

JKG Dhont, WJ Briels - Rheologica acta, 2008‏ - Springer
Abstract “Banded structures” of macroscopic dimensions can be induced by simple shear
flow in many different types of soft matter systems. Depending on whether these bands …

Rheo NMR and shear banding

PT Callaghan - Rheologica Acta, 2008‏ - Springer
The phenomenon of shear banding in complex fluids has been investigated using NMR
velocimetry and NMR spectroscopy, mostly in wormlike micelle systems, but more recently in …

Shear banding in time-dependent flows of polymers and wormlike micelles

RL Moorcroft, SM Fielding - Journal of Rheology, 2014‏ - pubs.aip.org
We study theoretically the formation of shear bands in time-dependent flows of polymeric
and wormlike micellar surfactant fluids, focussing on the protocols of step shear stress, step …

Shear banding in polymer solutions

M Cromer, MC Villet, GH Fredrickson, LG Leal - Physics of Fluids, 2013‏ - pubs.aip.org
The current theoretical belief is that the steady-state shear banding in viscoelastic liquids
requires a non-monotonic constitutive relationship between shear stress and shear rate …
