Viscoelastic instabilities are of practical importance, and are the subject of growing interest.
Reviewed here are the fresh developments as well as earlier work in this area, organized …

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 …

Two-fluid dynamics is a challenging subject rich in physics and prac tical applications. Many
of the most interesting problems are tied to the loss of stability which is realized in …

We review progress and open challenges for a number of problems related to the Oldroyd B
model which are of current interest to the mathematical community. We discuss existence …

A combined experimental, numerical and theoretical investigation of the geometric scaling of
the onset of a purely elastic flow instability in serpentine channels is presented. Good …

Model experiments were performed to determine the controlling parameters in the evolution
of the phase morphology of immiscible polymer blends from pellets to micrometre-sized …

Superposed plane Poiseuille flow of an incompatible polymer system consisting of
polypropylene and high‐density polyethylene has been investigated. Using the apparatus …

Purely viscous and purely elastic interfacial instabilities as well as the layer encapsulation
phenomena in superposed pressure-driven channel flow of well characterized Newtonian …

We examine the linear stability of the gravity-driven flow of a viscoelastic fluid film down an
inclined plane. The viscoelastic fluid is modeled using the Oldroyd-B constitutive equation …
