Filamentation of Unstable Vortex Structures via Separatrix Crossing: A Quantitative Estimate of Onset Time
The onset of filamentation for compact vortex structures in two-dimensional incompressible flows is elucidated. An estimate is presented for the filamentation time of an unstably perturbed Kirchhoff ellipse, obtained from a linear analysis of the geometry of the instantaneous corotating streamfunction.
