Abstract
Turbulent flows display intermittent pressure drops associated with vo rticity concentrations. Using wavelet transform, we characterize these low pressure events and study some of their statistical characteristi cs in a flow generated between the gap of two counter-rotating disks. We show that the mean frequency of intermittent pressure drops decreas es with increasing Reynolds number.
