TITLE: Hollow Vortices
TIME: 3:30 PM
LOCATION: GMCS 214
SPEAKER: Dr. Stefan Llewellyn Smith. UCSD
Hollow vortices are vortices whose interior is at rest. They posses vortex
sheets on their boundaries and can be viewed as a desingularization of
point vortices. After giving a history of point vortices, we obtain exact
solutions for hollow vortices in linear and nonlinear strain and examine
the properties of streets of hollow vortices. The former can be viewed as a
canonical example of a hollow vortex in an arbitrary flow, and its
stability properties depend. In the latter case, we reexamine the hollow
vortex street of Baker, Saffman and Sheffield and examine its stability to
arbitrary disturbances, and then investigate the double hollow vortex
street. Implications and extensions of this work are discussed.
