Flow velocity profiles and shear banding onset in a semidilute wormlike micellar system under Couette flow.
Velocity profiles in Couette flow are measured in a wormlike micellar solution made of cetyltrimethylammonium bromide (CTAB), sodium salicylate (NaSal), and water, at R (= [NaSal]/[CTAB]) = 2 and at R = 4; [CTAB] = 100 mM. Velocity profiles were obtained by using a two-incident beam laser Doppler technique. Profiles reveal that one of the micellar solutions (R = 2) becomes heterogeneous a long ...
متن کاملInertio-elastic instability in Taylor-Couette flow of a model wormlike micellar system
In this work, we use flow visualization and rheometry techniques to study the dynamics and evolution of secondary flows in a model wormlike micellar solution sheared between concentric cylinders, i.e., in a Taylor-Couette (TC) cell. The wormlike micellar solution studied in this work contains cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal). This system can be shear banding a...
متن کاملRheo-PIV of a Shear-Banding Wormlike Micellar Solution under Large Amplitude Oscillatory Shear
We explore the behavior of a wormlike micellar solution under both steady and large amplitude oscillatory shear (LAOS) in a cone–plate geometry through simultaneous bulk rheometry and localized velocimetric measurements. First, particle image velocimetry is used to show that the shear banded profiles observed in steady shear are in qualitative agreement with previous results for flow in the con...
متن کاملTransient evolution of shear-banding wormlike micellar solutions
A series of experiments were performed to further investigate the phenomenon of shear-banding in surfactant solutions. Many surfactant solutions, hrough their unique amphiphilic chemistry, form long wormlike micelle structures which behave like living polymers. These wormlike micelles ave interesting viscoelastic properties and have been the subject of a number of recent studies. These water-ba...
متن کاملSlippage and migration in Taylor–Couette flow of a model for dilute wormlike micellar solutions
9 We explore the rheological predictions of a constitutive model developed for dilute or semi-dilute worm-like micellar solutions in an axisymmetric Taylor–Couette flow. This study is a natural continuation of earlier work on rectilinear shear flows. The model, based on a bead-spring microstructure with non-affine motion, reproduces the pronounced plateau in the stress–strain-rate flow curve th...
