Vortex tubes in velocity fields of laboratory isotropic turbulence

Fluid Dynamics 2009-11-06 v1

Abstract

The streamwise and transverse velocities are measured simultaneously in grid turbulence at Reynolds numbers 100-300. We extract typical intermittency patterns, which are consistent with velocity profiles of Burgers and Lamb-Oseen vortices. The radii of these vortex tubes are estimated to be several of the Kolmogorov length.
