Abstract-
Fundamental to the study of bluff body flows is the formation
of vortices in the wake. Of primary concern here is the
interaction of this formation process with the motion of
a circular cylinder when the frequency of the motion is near
the frequency of normal vortex shedding. First, the basics of
the vortex formation process will be illustrated using the starting cylinder
flow. Then formation will be presented for both transverse-only and
figure-eight
oscillations, the latter being considered the more natural motion. In
addition, the observed phase and mode changes in the wake
will be addressed in terms of formation.
