VORTEX DYNAMICS IN THE CYLINDER WAKE
Since the review of periodic flow phenomena by Berger & Wille (1972), there has been a surge of activity regarding bluff body wakes. Many of the questions regarding wake vortex dynamics from the earlier review have now been answered in the literature, and perhaps an essential key to new understandings and to new questions has been the recent focus, over the past eight years, on the three-dimensional aspects of nominally two-dimensional wake flows. New techniques in experiment, using laser-induced fluorescence and particle image velocimetry, are vigorously being applied to wakes, but interestingly, several of the new discoveries have come from careful use of classical methods. There is no question that strides forward in understanding of the wake problem are being made possible by ongoing three-dimensional direct numerical simulations, as well as by the surprisingly successful use of analytical modelling in these flows, and by secondary stability analyses. These new developments, and the discoveries of several new phenomena in wakes, are presented in this review.
