Vortex shedding and its control
The fluid flow past the object creates alternating low-pressure vortices on the downstream side of the object. The object will tend to move toward the low- ...
Vortex Shedding - an overview | ScienceDirect Topics
Vortex shedding is a phenomenon, when the wind blows across a structural member, vortices are shed alternately from one side to the other.
Vortex shedding suppression and wake control: A review
There are various methods to control the wake structure and vortex shedding, such as employing an external small element, modifying geometry of ...
When air flows around an object, there is a range of flow velocities for which a von Karman vortex street is formed. The shedding of these vortices imparts a ...
