Timescales in shear banding of wormlike micelles
O. Radulescu, P. D. Olmsted, J. P. Decruppe +3
We show the existence of three well defined time scales in the dynamics of wormlike micelles after a step between two shear rates on the stress plateau. These time scales are compa…
Dynamical Coarse-Graining of Highly Fluctuating Membranes under Shear Flow
Simon W. Marlow, Peter D. Olmsted
The effect of strong shear flow on highly fluctuating lamellar systems stabilized by intermembrane collisions via the Helfrich interaction is studied. Advection enters the microsco…
Kinetics of the shear banding instability in startup flows
Suzanne M. Fielding, Peter D. Olmsted
Motivated by experiments on wormlike micelles, we study the early stages of the shear banding instability using a two-fluid Johnson-Segalman model. We perform a linear stability an…
The Effect of Shear Flow on the Helfrich Interaction in Lyotropic Lamellar Systems
Simon W. Marlow, Peter D. Olmsted
We study the effect of shear flow on the entropic Helfrich interaction in lyotropic surfactant smectic fluids. Arguing that flow induces an effective anisotropic surface tension in…
Early stages of the shear banding instability in wormlike micelles
Suzanne M. Fielding, Peter D. Olmsted
We study the early stages of the shear banding instability in semidilute wormlike micelles using the non-local Johnson-Segalman model with a two-fluid coupling of the concentration…
