Define vortex shedding
WebVortex definition, a whirling mass of water, especially one in which a force of suction operates, as a whirlpool. See more. WebFrequency of the vortex shedding, which is otherwise called as Strouhal frequency is dependent on the Strouhal number (S) and is given as follows: (3.6) where Vc is the current velocity and D is the diameter of the cylinder member. An inverse of the Strouhal shedding frequency is termed Strouhal shedding period.

WebMar 9, 2024 · Definition of Vortex Shedding. Vortex shedding is the phenomenon in which vortices are shed alternatively at either side of a bluff body at a certain frequency, and consequently the wake has an appearance of a vortex street as illustrated in Fig. 1. Fig. 1. WebPeriodic vortex shedding, also known as Karman vortex shedding, is a common phenomenon that occurs in the wake of a nominally two dimensional bluff body due ...
