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 …

A minute amount of long-chain flexible polymer dissolved in a turbulent flow can drastically
change flow properties, such as reducing the drag and enhancing mixing. One fundamental …

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 …

We use direct numerical simulations to study homogeneous and isotropic turbulent flows of
dilute polymer solutions at high Reynolds and Deborah numbers. We find that for small …

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

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 …

Drag reduction by dilute polymer solutions is the most recognized phenomenon in wall-
bounded turbulent flows, which is associated with large scales (eg, velocity scales) in spite …

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 studied the effects of long-chain polymers on the small scales of turbulence by
experimental measurements of Lagrangian accelerations in the bulk of turbulent flows of …

We investigate theoretically the near-wall region in elastic turbulence of a dilute polymer
solution in the limit of large Weissenberg number. As has been established experimentally …
