Spectra develop scale separ<strong>at</strong>ion andinertial ranges <strong>at</strong> l<strong>at</strong>e time.Separ<strong>at</strong>ion > 10 for t/τ > 19. Kolmogorov spectrum for w.WC-IWPCTM10-12

Peak <strong>of</strong> energy spectrum follows a k -2 trajectory once theflow becomes self-similar. (see Olivier Poujade’s talk)WC-IWPCTM10-13
