AbstractA feature of laminar separated flows which occurs naturally, even at rather small Reynolds numbers, is their instability. Thus, a mean flow pattern in a separated flow as well as its unsteady properties depend primarily on the instability and other ‘transitional’ phenomena associated with a laminar separation. This review presents the results of studies of this feature. Several transitional problems like those found in transition researches for other boundary-layer flows are also considered. These are: the receptivity of separated flows to external excitation, linear instability and non-linear wave interactions in a separation region. Feedback effects which are important for such flows are also discussed. Finally, the control of laminar separated flows based on the effect of external excitation on the transition is touched upon.
