In this review, I present an idiosyncratic view of the current state of shear banding in complex
fluids. Particular attention is paid to some of the outstanding issues and questions facing the …

Analytical solutions are presented for the flow of viscoelastic fluids in micron sized ducts,
namely between parallel plates and pipes under the combined influence of electrokinetic …

We study the Johnson–Segalman (JS) model as a paradigm for some complex fluids which
are observed to phase separate, or “shear band” in flow. We analyze the behavior of this …

Under steady shear flow, elongated micellar solutions show shear stress saturation above a
critical shear rate due to the formation of shear bands that result in non-homogeneous flow …

In this paper, we use rheometry and flow visualization to study the dynamics of the interface
between shear bands in a wormlike micellar solution sheared between concentric cylinders …

We present analytic solutions for steady flow of the Johnson–Segalman (JS) model with a
diffusion term in various geometries and under controlled strain rate conditions, using …

The stability of two representative constitutive equations for polymer melts, the exponential
Phan-Thien–Tanner (PTT) model and the Giesekus model, are investigated in planar shear …

Concentrated multiarm star polymer solutions are used in this work as prototype, well
defined, systems that clearly exhibit viscoplasticity and thixotropy. A thermodynamically …

For certain values of the material parameters, certain viscoelastic fluid models allow for a
nonmonotonic relationship between the shear stress and shear rate in simple flows. We …

Two solutions are presented for fully-developed pipe and planar flows of multimode
viscoelastic models. The fluids have a Newtonian solvent contribution and the polymer …
