Abstract

This paper addresses the wake-induced instability of a pair of elastically mounted cylinders with one located in the other’s wake. In particular, the effort is made to investigate the different instability mechanisms of the downstream cylinder in the near or far wake field of the upstream cylinder. It is found that the fluid-elastic instability of the downstream cylinder can be caused by either a Hopf or a stationary bifurcation, depending upon its position relative to the upstream cylinder.
