- SEE THE SPEEDING VORTICES (AVI MOVIE)
The movie shows shear flow past a cylinder. Vortices in the lower row split into two. One vortex remains in the lower row while the other one is transported to the other side where it is accelerated by the larger vortices, moving much faster than them. An asymmetric vortex street is formed. (From Peppa, Kaiktsis, and Triantafyllou, BBVIV IV 2005)
- NORMAL MODES OF VORTEX-INDUCED VIBRATIONS(ANIMATED GIF)
The animated gif shows a typical normal mode of vibration of a flexible structure in a current. Unlike vibrations in still fluid which are standing waves, VIV modes have the form of traveling waves. The animated gif shows synchronization of the second natural mode with the current.
