Professor Monika Nitsche

speaks on

Vortex Sheet motion and the formation of Vortex Rings

Abstract.A vortex sheet is a mathematical model for a shear layer in which the finitely thick layer is approximated by a surface. Ideally, the solution to the model equations approximates the solution to the real viscous flow equations in the limit of zero viscosity. I will first present the numerical issues that arise in solving the model vortex sheet equations, and then study applications to simulate a real viscous flow, the formation of a vortex ring.

Tea. High tea will be served at 3:30pm in the Lounge.
Emmy's. Certain refreshments will be available at Emmy's after the talk.
Host. Dan Rockmore is the host. Anybody who is interested in having dinner with the speaker should contact Dan at 6-3260.
