Absolute instabilities and self-sustained oscillations in the wake of circular cylinders
Journal Article
·
· Phys. Rev. Lett.; (United States)
The Karman vortex street in the wake of a circular cylinder is shown to be due to an absolute instability of the flow in the near wake. A new means of instability analysis is used, involving mappings from the complex k plane to the complex ..omega.. plane.
