Abstract:

The near-wall region of bounded turbulent flows consists of stream- wise vortices, low speed streaks, intense shear layers, inflectional velocity profiles, oscillations and ejections of low speed fluid out into the logarithmic layer. Although a mass of data has accumulated over the past 25 years concerning this important chain of events, the general picture is still suggestive rather than conclusive. Some proposals are offered as means of interacting with andor interrupting the sequence of these events in the wall region.
