Abstract
Flow past a cylinder beneath a free surface gives rise to
fundamental classes of nearwake structure that are distinctly different
from the wake of a completely submerged cylinder. A central feature is
the generation of a vorticity layer from the free surface due to:
localized separation, in the form of small-scale breaking of a
free-surface wave; or complete separation from the free surface. This
vorticity layer appears adjacent to a layer from the surface of the
cylinder, thereby forming a jet-like flow. It is shown that the
instantaneous vorticity flux on either side of this jet is rapidly
balanced immediately after the onset of separation from the free
surface.
