摘要
The streamwise and transverse velocities are measured simultaneously in grid turbulence at Reynolds numbers 100-300 We extract typical intermittence 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. (C) 2000 Elsevier Science B.V. All rights reserved.
