Structure and Stability of Streets of Finite Vortices,pairs, single rows and the staggered double row are considered. The stability of the flows to two-dimensional disturbances is examined. In particular, it is shown that finite area stabilises the Karman vortex street for a finite band of aspect ratio values about the Karman value of 0.281.

Wave Propagation, Instability, and Breakdown of Vortices,cent theoretical and experimental work provide evidence that waves and instabilities are important elements of the vortex breakdown process. Breakdown of vortex cores at high Reynolds numbers may occur in one of two forms, the apparently axisymmetric (“bubble”) or the “spiral” form. The application

Analogies between Oscillation and Rotation of Bodies Induced or Influenced by Vortex Shedding,o rotate or oscillate, vortex shedding can strongly influence the periodic characteristics of the flow. This paper discusses various degrees of analogies or similarities between rotating and oscillating bodies with vortex shedding in a parallel flow, with respect to both the physical phenomena invol
