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 …

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 …

We experimentally investigate the flow of a viscoelastic fluid in a parallel shear geometry at
low Reynolds number. As the flow becomes unstable via a nonlinear subcritical instability …

The dissolution of minute concentration of polymers in wall-bounded flows is well-known for
its unparalleled ability to reduce turbulent friction drag. Another phenomenon, elasto-inertial …

Two-dimensional channel flow simulations of FENE-P (finitely extensible nonlinear elastic-
Peterlin) fluid in the elasto-inertial turbulence (EIT) regime reveal distinct regimes ranging …

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 …

Turbulence is ubiquitous in nature, yet even for the case of ordinary Newtonian fluids like
water, our understanding of this phenomenon is limited. Many liquids of practical importance …

By quantitative studies of statistics of polymer stretching in an elastic turbulence and the
statistical properties of this random flow itself that are characterized by the average …

We consider the dynamics of a polymer with finite extensibility placed in a chaotic flow with
large mean shear, to explain how the polymer statistics changes with Weissenberg number …
