Abstract Steady shear and rheo-optical experimental data measured in several micellar solutions, demonstrate the existence of a non-equilibrium critical point (necp) in the shear banding flow of wormlike micellar solutions by the following evidence: (1) the disappearance of the coexistence of two steady banded fluids at the necp, (2) the curves of the reduced shear stress versus reduced shear rate become anti-symmetric in the neighborhood of the non-equilibrium critical point; (3) flow… Expand
Derivation of the mechanical and thermodynamic potentials from the generalized BMP model under shear-banding flow

Flows of living polymer fluids.
It is underline how a more "hydrodynamical perspective" has emerged by making fruitful analogies with elastic and inertio-elastic instabilities known in solutions of regular polymers and how this new perspective constrains theoretical modelling and calls for the use of new tools of investigation.
