Abstract Employing laser Doppler anemometry and VITA techniques, the bursting frequency in
turbulent boundary layers has been measured over the Reynolds-number range 320 to 1470. The result
indicates that the mean and non-dimensional bursting frequency scaled with the variables appropriate for the
wall region was constant and independent of Reynolds number. When the same data are plotted using the
outer variables of boundary layer tO normalize the bursting frequency, the non-dimensional frequency
increases as the Reynolds number increases. This is in agreement with the results of Blaekwelder et al. (1983)
who used hot wire anemometry and VITA technique.
