Viscoelastic plane Poiseuille flow is shown to become linearly unstable in the absence of
inertia, in the limit of high elasticities, for ultradilute polymer solutions. While inertialess …

We shortly describe the main results on elastically driven instabilities and elastic turbulence
in viscoelastic inertialess flows with curved streamlines. Then we describe a theory of elastic …

Creeping flow of polymeric fluid without inertia exhibits elastic instabilities and elastic
turbulence accompanied by drag enhancement due to elastic stress produced by flow …

This paper is an pedagogical essay on the scenario of the instabilities and the transition to
turbulence in visco-elastic polymer flows. When polymers are long, they get easily stretched …

Newtonian pipe flow is known to be linearly stable at all Reynolds numbers. We report, for
the first time, a linear instability of pressure-driven pipe flow of a viscoelastic fluid, obeying …

Elasto-inertial turbulence (EIT) is a new, two-dimensional chaotic flow state observed in
polymer solutions with possible connections to inertialess elastic turbulence and drag …

The goal of the present study is threefold:(i) to demonstrate the two-dimensional nature of
the elasto-inertial instability in elasto-inertial turbulence (EIT),(ii) to identify the role of the …

A modal stability analysis shows that pressure-driven pipe flow of an Oldroyd-B fluid is
linearly unstable to axisymmetric perturbations, in stark contrast to its Newtonian counterpart …

Elastic turbulence is a chaotic flow state observed in dilute polymer solutions in the absence
of inertia. It was discovered experimentally in circular geometries and has long been thought …

When subjected to sufficiently strong velocity gradients, solutions of long, flexible polymers
exhibit flow instabilities and chaotic motion, often referred to as elastic turbulence. Its …
