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 …

Since the seminal work of Taylor in 1923, Taylor–Couette (TC) flow has served as a
paradigm to study hydrodynamic instabilities and bifurcation phenomena. Transitions of …

We experimentally investigate the flow of a viscoelastic fluid in a parallel shear geometry at
low Reynolds number. As the flow becomes unstable via a nonlinear subcritical instability …

Wormlike micellar surfactant solutions are encountered in a wide variety of important
applications, including enhanced oil recovery and ink-jet printing, in which the fluids are …

We employ time-resolved flow velocimetry and birefringence imaging methods to study the
flow of a well-characterized shear-banding wormlike micellar solution around a novel glass …

The lid-driven cavity flow is a well-known benchmark problem for the validation of new
numerical methods and techniques. In experimental and numerical studies with viscoelastic …

The flow of viscoelastic fluids in channels and pipes remains poorly understood, particularly
at low Reynolds numbers. Here, we investigate the flow of polymeric solutions in straight …

The rheology and shear-induced structures of a series of self-assembled surfactant wormlike
micelles (WLMs) with varying levels of branching are measured using rheo-and flow-small …

Shear thickening corresponds to an increase of the viscosity as a function of the shear rate. It
is observed in many concentrated suspensions in nature and industry: water or oil saturated …
