Role of Micellar Entanglement Density on Kinetics of Shear Banding Flow Formation: Experiments and a Comparison with the VCM model

  title={Role of Micellar Entanglement Density on Kinetics of Shear Banding Flow Formation: Experiments and a Comparison with the VCM model},
  author={Peter Rassolov and Lin Zhou and Pamela Cook and Hadi Mohammadigoushki},
We investigate the effects of micellar entanglement density on the kinetics of shear banding flow formation in a Taylor-Couette flow via a combination of experiments and simulations of the Vasquez-Cook-McKinley (VCM) model. In experiments, three sets of wormlike micellar solutions, each set with a similar fluid elasticity and zero-shearrate viscosity, but with varying entanglement densities, are studied under start-up of steady shear. Our experiments indicate that in the set with the low fluid…

Kinetics of Shear Banding Flow Formation in Linear and Branched Wormlike Micelles
While elastic instabilities in the linear solution emerge in the high shear band, the flow of branched solution at high Wi becomes unstable due to end effects, with growing end regions that ultimately span the entire axial length of the TC cell.


Effects of elasticity and flow ramp up on kinetics of shear banding flow formation in wormlike micellar fluids
We report experiments on spatiotemporal evolution of the velocity profiles in shear-banding wormlike micelles upon inception of the flow in a Taylor–Couette (TC) cell. Both moderately entangled and

Interplay between elastic instabilities and shear-banding: three categories of Taylor–Couette flows and beyond
In the past twenty years, shear-banding flows have been probed by various techniques, such as rheometry, velocimetry and flow birefringence. In micellar solutions, many of the data collected exhibit
Multiple Shear-Banding Transitions for a Model of Wormlike Micellar Solutions
The interplay of the competing roles of inertia, the imposed shear rate, and the transient dynamics of the start up in the flow are examined using the VCM (Vasquez- Cook-McKinley) model, a scission/reforming network model developed to capture the essential physics of the deformable micellar microstructure and its coupling to the macroscopic flow field.
