 abstract = {The existence of drag reduction by polymer additives, well established
for wall-bounded turbulent flows, is controversial in homogeneous,
isotropic turbulence. To settle this controversy, we carry out a
high-resolution direct numerical simulation of decaying, homogeneous,
isotropic turbulence with polymer additives. Our study reveals clear
manifestations of drag-reduction-type phenomena: On the addition of
polymers to the turbulent fluid, we obtain a reduction in the
energy-dissipation rate, a significant modification of the fluid energy
spectrum especially in the deep-dissipation range, a suppression of
small-scale intermittency, and a decrease in small-scale vorticity
filaments.},
