Abstract

We measured inertial and dissipation range statistics in the decaying turbulence generated by a bi-planar grid of crossed bars in a wind tunnel. We did so at Taylor Reynolds numbers between 60 and 1700, reaching higher than any previous experimental study of homogeneous and isotropic turbulence. The measurements were made in the Variable Density Turbulence Tunnel (VDTT) at the Max Planck Institute in Göttingen with both traditional hot-wire anemometers and nano-fabricated NSTAP anemometers developed at Princeton University. The data confirm that even when the large-scale conditions are controlled as the Reynolds number is raised, scaling ranges are not well-defined unless Extended Self-Similarity is employed. We also find a universal transition between the inertial and the near-dissipation ranges.
