Structure of the most singular vortices in fully developed turbulence
S. I. Vainshtein, K. R. Sreenivasan
Abstract
Using high Reynolds number experimental data, we search for most dissipative, most intense vortices. These structures possess a scaling predicted by log-Poisson model for the dissipation field εr. These new experimental data suggest that the most intense structures have co-dimension less than 2. The log-Poisson statistics is compared with log-binomial which follows from the random β-model.
