Lagrangian chaos and the enstrophy cascade in Ekman-Navier-Stokes two-dimensional turbulence
Francesco Michele Ventrella, Victor de Jesus Valadão, Guido Boffetta +2
Two-dimensional turbulence with linear (Ekman) friction exhibits spectral properties that deviate from the classical Kraichnan prediction for the direct enstrophy cascade. In parti…

Scaling and Predictability in Surface Quasi-Geostrophic Turbulence
V. J. Valadão, F. De Lillo, S. Musacchio +1
Turbulent flows are strongly chaotic and unpredictable, with a Lyapunov exponent that increases with the Reynolds number. Here, we study the chaoticity of the Surface Quasi-geostro…

Vortex Gas Modeling of Turbulent Circulation Statistics
G. B. Apolinário, L. Moriconi, R. M. Pereira +1
Statistical properties of circulation encode relevant information about the multi-scale structure of turbulent cascades. Recent massive computational efforts have posed challenging…
