We review three different types of viscoelastic surface instabilities: The Rayleigh–Plateau,
the Saffman–Taylor and the Faraday instabilities. These instabilities are classical examples …

In this manuscript we present experimental data and quantitative analysis for the fingering
instability along the interface of finite volume of Newtonian (mineral oil) and dilute shear …

The viscous fingering instability, which forms when a less-viscous fluid invades a more-
viscous one within a confined geometry, is an iconic system for studying pattern formation …

We theoretically study the linear stability of the Saffman–Taylor problem where a viscous
Newtonian fluid (with viscosity η l) displaces an Upper Convected Maxwell (UCM) fluid (with …

The displacement of a shear-thinning fluid by a denser and less viscous Newtonian fluid in a
vertical duct is investigated using experiments and numerical simulations. We study how …

The performance of non-thermal, cold, heavy oil production methods, such as waterflooding
or gas injection (foamy oil) applications, is predominantly limited. As an alternative, efficient …

In this paper, the well-known Saffman-Taylor instability of an immiscible quasilinear
viscoelastic-Newtonian displacement in a Hele-Shaw cell is studied numerically for the first …

The response of a two-dimensional liquid foam to a localized air injection is investigated
experimentally and theoretically. The experiments show a rich phenomenology, with two …

Viscous fingering (VF) at the interface of two immiscible fluids can have disruptive effects in
many technological applications. Therefore finding methods for reducing it with an effective …

In reacting flows where chemical reactions occur within a flowing fluid, certain changes in
the properties of the fluid, induced by the chemical reaction, can alter the flow dynamics …
