The flow of polymer solutions is examined in a flow geometry where a jet is used to inject the
viscoelastic solution into a cylindrical tube. We show that this geometry allows for the …

Following our first report (A Groisman and V Steinberg 2000 Nature 405 53), we present an
extended account of experimental observations of elasticity-induced turbulence in three …

Turbulence in dilute polymer solutions when polymers are strongly stretched by the flow is
investigated. We establish power-law spectra of velocity, that are not associated with a flux …

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 …

A viscous solvent laminar flow may be strongly modified by the addition of a tiny amount of
long polymer molecules, resulting in a chaotic flow called elastic turbulence (ET). ET is …

Injected power P and pressure p fluctuations in a swirling flow of polymer solutions in a wide
range of polymer concentrations c in elastic turbulence regime show non-Gaussian statistics …

The small-scale statistics of homogeneous isotropic turbulence of dilute polymer solutions is
investigated by means of direct numerical simulations of a simplified viscoelastic fluid model …

Turbulence is a ubiquitous phenomenon that is not fully understood. It is known that the flow
of a simple, newtonian fluid is likely to be turbulent when the Reynolds number is large …

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 …

We investigate theoretically and numerically the effect of polymer additives on two-
dimensional turbulence by means of a viscoelastic model. We provide compelling evidence …
