INSTABILITY OF THREE ROW VORTEX STREETS,
Abstract
The steady solution of three row vortex streets with equal spacing between two adjacent vortices in the same row is shown to be of a standard configuration with arbitrary ratio of the spacing to the distance between one pair of the streets. It is shown that for any ratio such configurations are always unstable. When the strength of vortices in one row vanishes and we drop the requirement of stability of motion of the vortices with zero strength, the steady configuration of the remaining two vortices is stable and becomes the Karman vortex street.
