Survival distribution of the stretching and tilting of vortical structures in isotropic turbulence. Anisotropic filtering analysis

Daniela Tordella, Luca Sitzia, Silvio Di Savino

Using a Navier-Stokes isotropic turbulent field numerically simulated (Biferale et al., Phys. Fluids (2005)), we show that the probability of having a stretching-tilting larger tha…
