@article{ISI:000286750700001, abstract = {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 manifestations of dissipation-reduction 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; and signatures of the suppression of small-scale structures, including a decrease in small-scale vorticity filaments. We also compare our results with recent experiments and earlier DNS studies of decaying fluid turbulence with polymer additives.}, article-number = {066313}, author = {Perlekar, Prasad and Mitra, Dhrubaditya and Pandit, Rahul}, doi = {10.1103/PhysRevE.82.066313}, eissn = {1550-2376}, issn = {1539-3755}, journal = {PHYSICAL REVIEW E}, month = {DEC 27}, number = {6, 2}, times-cited = {28}, title = {Direct numerical simulations of statistically steady, homogeneous, isotropic fluid turbulence with polymer additives}, unique-id = {ISI:000286750700001}, volume = {82}, year = {2010} }
