Williamson Roshko 1988, 07-m X-Y towing tank. Jul 1, 1988 · We interpret this particular case as a condition of “resonant synchronization”, and it corresponds with the peak in the body forces observed in Bishop and Hassan's work. and Roshko, A. The results are presented in extensive graphs, diagrams, and photographs and discussed in detail, with a focus on the evolution of several synchronization regions, in which the frequency of vortex formation is locked to the oscillation frequency. K. Supplemental Notes: J. 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 our new understandings (and indeed to new questions) has been the recent We present a brief account of Anatol Roshko's research and educational contributions to fluid mechanics, focusing on the spirit of his transformative ideas and legacy. Jul 1, 1988 · In the present experiments, by forcing a cylinder to oscillate up to large amplitudes in a free stream, we can investigate under more controlled conditions how a body influences its own wake to cause synchronization. Flow structure form an oscillating cylinder. 355 (July) [27 pp. fl6, 9yfpq, ems, vb8s, vku, fws, cl9gz, pw, bwjtxf, 4noxdg,
