Abstract

Spanwise velocity statistics from high-Reynolds-number turbulent boundary layers are reported. The dataset combines efforts spanning over a decade at the University of Melbourne to accurately capture Reynolds number trends for the spanwise velocity, nominally over one order of magnitude change in, using custom subminiature cross-wire probes that minimise spatial resolution effects and misalignment errors. The spanwise velocity variance is found to exhibit an invariant logarithmic slope in the log region, in a similar manner to the streamwise velocity, which is consistent with the existence of self-similar features within wall-bounded flows. However, unlike the-variance, it appears that the l..
