In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from … See more
The frequency at which vortex shedding takes place for a cylinder is related to the Strouhal number by the following equation:

On the Origins of Vortex Shedding in Two-dimensional …
Two simple and intuitive, but quite general, mechanisms, termed the Vortex-Shedding Mechanism (VSM) and its special case, the Pressure-Gradient Mechanism (PGM), describing vortex or …
Shedding patterns in the wake of oscillating cylinders are distinct and exist for a certain range of heave frequencies and amplitudes. The different modes have a great impact on structural …
shedding begins to lose coherence around Re =105 as turbulence invades the flow from the wake. Because it occurs over such a wide range of Reynolds numbers (and object shapes), …
Vortex Shedding in Air | Harvard Natural Sciences Lecture …
A thin wire, moving through the air, is made to vibrate in the audio range at the vortex shedding frequency. When air flows around an object, there is a range of flow velocities for which a von …
Vortex shedding is a complex physical phenomenon, especially when it degenerates into lock-in condition. As large vibrations may occur at moderate and frequent wind velocities, structures …
Vortex Shedding in Water | Harvard Natural ... - Harvard University
Water moving around a cylindrical pendulum makes the cylinder swing at the vortex shedding frequency. When fluid flows around a cylindrical object, there is a range of flow velocities for …
