Inertio-elastic instability of non shear-banding wormlike micelles
Christophe Perge, Marc-Antoine Fardin, Sebastien Manneville
Homogeneous polymer solutions are well-known to exhibit viscoelastic flow instabilities: purely elastic when inertia is negligible, inertio-elastic otherwise. Recently, shear-bandi…
Shear-induced structures versus flow instabilities
Marc-Antoine Fardin, Christophe Perge, Nicolas Taberlet +1
The Taylor-Couette flow of a dilute micellar system known to generate shear-induced structures is investigated through simultaneous rheometry and ultrasonic imaging. We show that f…
Surfactant micelles: model systems for flow instabilities of complex fluids
Christophe Perge, Marc-Antoine Fardin, Sebastien Manneville
Complex fluids such as emulsions, colloidal gels, polymer or surfactant solutions are all characterized by the existence of a "microstructure" which may couple to an external flow…
Suppression of the Rayleigh-Plateau instability on a vertical fibre coated with wormlike micelle solutions
François Boulogne, Marc-Antoine Fardin, Sandra Lerouge +2
We report on the Rayleigh-Plateau instability in films of giant micelles solutions coating a vertical fibre. We observe that the dynamics of thin films coating the fibre could be v…
Ultrafast ultrasonic imaging coupled to rheometry: principle and illustration
Thomas Gallot, Christophe Perge, Vincent Grenard +3
We describe a technique coupling standard rheology and ultrasonic imaging with promising applications to characterization of soft materials under shear. Plane wave imaging using an…
