Abstract:

Contour dynamics is a boundary integral evolutionary method ideally suited to 2-D inviscid and nearly inviscid flows. Applications in many areas are described. Specific emphasis is given to the Euler equations. A large class of new steady-state solutions with piecewise constant vorticity is described, including singly-connected rotating and doubly-connected translating V-states. Examples of time dependent calculations are shown which exhibit merger and scattering. Keywords include Vortex dynamics and Reprints.
