SUMMARY:Evidence for finite dissipation during vortex reconnection - Rober

CONTACT:Edriss S. Titi
DESCRIPTION:This presentation will show evidence that growth of the volume
 -integrated enstrophy Z through\, then beyond\, the first reconnection of 
 isolated vortices is sufficient to first show convergence of √νZ. This 
 is followed by convergence of the dissipation rate ε=νZ over a finite ti
 me\, consistent with the existence of finite-time dissipation anomalies. B
 ut only so long as the domain size V increases as ν decreases. Also to be
  discussed are the evolution of spectra\, the helicity and the helicity tr
 ansfer.
