000014447 520__ $$2eng$$aLaminar boundary layers subjected to weak random excitations break down into turbulent motion through a succession of turbulent spots. The late stage of transition is therefore different from that observed when excitation is periodic, as is common in many investigations. The spot occurrence is not necessarily where the magnitudes of the perturbation time series are at a maximum. A series of experiments mapping out the flow oscillations that arise downstream from a pseudo-random driven point source are discussed. It would seem that the breakdown process obtained in these experiments mimics the naturally occurring behaviour observed when background system noise creates the disturbances.
