The interplay between boundary conditions and flow geometries in shear banding: hysteresis, band configurations, and surface transitions
J. M. Adams, S. M. Fielding, P. D. Olmsted
We study shear banding flows in models of wormlike micelles or polymer solutions, and explore the effects of different boundary conditions for the viscoelastic stress. These are ne…
Equilibrium Onions?
L. Ramos, D. Roux, P. D. Olmsted +1
We demonstrate the possibility of a stable equilibrium multi-lamellar (``onion'') phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvatu…
Spatio-temporal oscillations and rheochaos in a simple model of shear banding
Suzanne Fielding, Peter Olmsted
We study a simple model of shear banding in which the flow-induced phase is destabilised by coupling between flow and microstructure (wormlike micellar length). By varying the stre…
Flow phase diagrams for concentration-coupled shear banding
Suzanne M Fielding, Peter D Olmsted
After surveying the experimental evidence for concentration coupling in the shear banding of wormlike micellar surfactant solutions, we present flow phase diagrams spanned by shear…
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…
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…
