[PDF][PDF] Instabilities in wormlike micelle systems: From shear-banding to elastic turbulence

MA Fardin, S Lerouge - The European Physical Journal E, 2012 - Springer
Shear-banding is ubiquitous in complex fluids. It is related to the organization of the flow into
macroscopic bands bearing different viscosities and local shear rates and stacked along the …

[BOEK][B] Physics of buoyant flows: from instabilities to turbulence

MK Verma - 2018 - World Scientific
Hydrodynamic flows exhibit turbulent behaviour which is not well understood till date. When
a fluid is in a gravitational field, the flow becomes even more complex due to the gravity …

Torque in Taylor–Couette flow of viscoelastic polymer solutions

B Martínez-Arias, J Peixinho - Journal of Non-Newtonian Fluid Mechanics, 2017 - Elsevier
When a polymer solution is sheared between concentric cylinders, with the inner rotating

Stress diffusion in shear banding wormlike micelles

MA Fardin, O Radulescu, A Morozov, O Cardoso… - Journal of …, 2015 - pubs.aip.org
In order to deal with strong inhomogeneities of the polymer stress in shear banding of
wormlike micelles, rheological models usually include stress diffusion terms. These terms lift …
