Abstract
Measurements in laboratory rough wall turbulent boundary layers have been made over a sufficient Reynolds number range for independence on the Reynolds number to be established adequately. The data have been analyzed with respect to the average period between ejections and sweeps, using methods previously applied to smooth wall flows. The results clearly show that the period is independent of Reynolds number when it is scaled on outer variables.
