Prof. David G. Dritschel - Three point vortices: equilibria, instability, periodic motion, and mixing
February 27, Tuesday · 11:00 – 12:00AM
@Consiglio Nazionale delle Ricerche, Istituto di Ingegneria del Mare, Landrini Hall
Via di Vallerano 139, 00128 Roma
Abstract
Prof. Dritschel will discuss the integrable motion of three point vortices in planar, two-dimensional flows, together with the motion of tracer particles advected by the vortices. Aspects of the motion of three vortices are well known, but surprisingly the complete parameter space has not been fully explored, and it turns out to be exceedingly rich. The generally periodic motion of the vortices also has the potential to give rise to chaotic mixing, and examples of this will be presented.
Short bio
Prof. Dritschel is the Head of the Vortex Dynamics Research Group, at the University of St Andrews. He is the most influential researcher in Vortex Dynamics. His research combines theoretical analysis and numerical computation in the study of fundamental aspects of atmospheric and oceanic fluid dynamics, with particular regards to the vortex dynamics.
