@article{ISI:000297003500003, abstract = {We obtain, by extensive direct numerical simulations, time-dependent and equal-time structure functions for the vorticity, in both quasi-Lagrangian and Eulerian frames, for the direct-cascade regime in two-dimensional fluid turbulence with air-drag-induced friction. We show that different ways of extracting time scales from these time-dependent structure functions lead to different dynamic-multiscaling exponents, which are related to equal-time multiscaling exponents by different classes of bridge relations; for a representative value of the friction we verify that, given our error bars, these bridge relations hold.}, article-number = {184503}, author = {Ray, Samriddhi Sankar and Mitra, Dhrubaditya and Perlekar, Prasad and Pandit, Rahul}, doi = {10.1103/PhysRevLett.107.184503}, eissn = {1079-7114}, issn = {0031-9007}, journal = {PHYSICAL REVIEW LETTERS}, month = {OCT 26}, number = {18}, times-cited = {13}, title = {Dynamic Multiscaling in Two-Dimensional Fluid Turbulence}, unique-id = {ISI:000297003500003}, volume = {107}, year = {2011} }
