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 …

This review highlights the profound and unexpected ways in which viscosity varying in
space and time can affect flow. The most striking manifestations are through alterations of …

Viscosity regularisation methods are probably the most popular current method for
computing visco-plastic fluid flows. They are however generally used in an ad hoc manner …

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 …

There is extensive literature on the stability of parallel two-phase flow, both in the context of
liquid-liquid as well as gas-liquid flow. Aimed at making this literature more transparent, this …

The regimes of drop generation were studied in a Dolomite microfluidic device which
combined both hydrodynamic and geometrical flow focusing over a broad range of flow …

Linear stability of stratified two-phase flows in horizontal channels to arbitrary wavenumber
disturbances is studied. The problem is reduced to Orr-Sommerfeld equations for the stream …

The linear stability characteristics of pressure-driven two-layer channel flow are considered,
wherein a Newtonian fluid layer overlies a layer of a Herschel-Bulkley fluid. A pair of …

A low-dimensional model capturing the fully coupled dynamics of a wavy liquid film in
interaction with a strongly confined laminar gas flow is introduced. It is based on the …

The linear stability of the two-layer flow of immiscible, incompressible fluids in an inclined
channel is considered. In the long-wave limit, mechanisms for linear instability, and the …
