Supercomputer computation of vortex shedding due to
unsteady flow separation.
Alternating vortex shedding takes place from sides of the cylinder in a
wide range of Reynolds number. They form staggered rows of vortices that
are commonly called "Karman vortex street."
These vortex sheddings from bluff-bodies like the circular cylinder shown
here are responsible for structure vibrations and wind noise, like the whistling
of power and telephone lines.
