Even in simple geometries, many complex fluids display nontrivial flow fields, with regions
where shear is concentrated. The possibility for such shear banding has been known for …

The Oldroyd-B model has been used extensively to predict a host of instabilities in shearing
flows of viscoelastic fluids, often realized experimentally using polymer solutions. The …

Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

In this review, we report recent developments on the shear-induced transitions and
instabilities found in surfactant wormlike micelles. The survey focuses on the nonlinear …

Many soft materials, including microgels, dense colloidal emulsions, star polymers, dense
packings of multilamellar vesicles, and textured morphologies of liquid crystals, share the …

Rheological studies of low concentration (down to 0.1%) poly (acrylonitrile)(PAN)–dimethyl
sulfoxide (DMSO) solutions revealed the existence of a rather unusual effect of the gel-like …

A multicomponent lattice Boltzmann model recently introduced [R. Benzi et al, Phys. Rev.
Lett. 102, 026002 (2009)] to describe some dynamical behaviors of soft-flowing materials is …

We report a novel inertia-less, elastic flow instability for a viscoelastic, shear-thinning
wormlike micellar solution flowing past a microcylinder in a channel with blockage ratio BR …

We study the dynamics of the Taylor-Couette flow of shear banding wormlike micelles. We
focus on the high shear rate branch of the flow curve and show that for sufficiently high …

We report on the flow dynamics of a wormlike micellar system (CPCl/NaSal/brine)
undergoing a shear-banding transition using a combination of global rheology, 1D …
