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

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 …

Turbulent-drag reduction in a dilute polymer solution has been studied using the technique
of photon-correlation homodyne spectroscopy to measure velocity differences in a …

We numerically investigate the spatial and temporal statistical properties of a dilute polymer
solution in the elastic turbulence regime, ie, in the chaotic flow state occurring at vanishing …

We carry out a direct numerical simulation (DNS) study that reveals the effects of polymers
on statistically steady, forced, homogeneous, and isotropic fluid turbulence. We find clear …

By tracking small particles in the bulk of an intensely turbulent laboratory flow, we study the
effect of long-chain polymers on the Eulerian structure functions. We find that the structure …

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 investigate high-Reynolds-number turbulence in dilute polymer solutions. We show the
existence of a critical value of the Reynolds number, which separates two different regimes …

Polymers are remarkable molecules that have relaxation times that can span 15 orders of
magnitude. The very longest of the relaxation times for high molecular weight polymers are …

The comparison of the results of direct numerical simulations of isotropic turbulence of
Newtonian and viscoelastic fluid provides evidence that viscoelasticity modifies qualitatively …
