Vortex dynamics sesquicentennial

The year 2008 will, in some sense, be the sesquicentennial of the field of vortex dynamics. Helmholtz's famous paper on the subject, "Über Integrale der hydrodynamischen Gleichungen, welche den Wirbelbewegungen entsprechen", published in Journal für die reine und angewandte Mathematik (vol. 55, 25–55, appeared in 1858.

Please use this blog to share your ideas on how we might appropriately celebrate the vortex dynamics sesquicentennial. (I have proposed an IUTAM symposium entitled "150 Years of Vortex Dynamics" to be held in 2008. More on that later.)

Classical and Quantum Vortex Rings

One of the six minisymposia to be held as part of the 22nd International Congress on Theoretical and Applied Mechanics, August 24-30, 2008, in Adelaide, Australia, is entitled "Classical and Quantum Vortex Rings". Convenors are Carlo Barenghi, University of Newcastle, and H.A. The usual format for minisymposia at IUTAM congresses is that they start off with 3-4 lectures of an "instructional character" and then continue with additional invited and submitted papers. The organizers hope for a lively and comprehensive set of sessions, ideally spanning the full week of the Congress.

Minisymposium on Vortex Dynamics

The 15th US National Congress on Theoretical and Applied Mechanics, held in Boulder, CO, June 25-30, featured a minisymposium on vortex dynamics with the following presentations:
  • H. Aref, Virginia Tech, “Vortex dynamics 150 years later”
  • D. Crowdy, Imperial College, “Point vortex motion in the presence of boundaries: new perspectives”
  • S. Tung, U Colorado, “Vortices in rotating BECs”
  • R. Donnelly, U Oregon, “Quantum turbulence”
  • P. K. Newton, USC, “Heterogeneous equilibrium configurations of N-Point vortices on the sphere”
  • L. Zanetti, Politecnico di Torino, “Vortex equilibria in confined domains”
  • M. A. Stremler, Vanderbilt U, “Analytical models of vortex wakes”
  • V. V. Meleshko, University of Kiev, “Near wall control and transport properties of two-dimensional vortex structures”
