“The von Kármán vortex street is one of the most prominent and exquisite flow patterns observed in fluid dynamics. For a fluid flow past a cylinder (and other bluff bodies), flow separation and eventually alternating vortex shedding are observed in the wake at large Reynolds numbers where fluid inertia dominates the flow.” https://journals.aps.org/prfluids/abstract/10.1103/dsx8-n7mr Yahya Modarres-Sadeghi E Professor of Mechanical Engineering, University of Massachusetts Amherst | Shamoon Ahmed
