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…

Spectrum correction in Ekman-Navier-Stokes turbulence
V. J. Valadão, G. Boffetta, F. De Lillo +2
The presence of a linear friction drag affects significantly the dynamics of turbulent flows in two-dimensions. At small scales, it induces a correction to the slope of the energy…

Manipulating the direction of turbulent energy flux via tensor geometry in a two-dimensional flow
Xinyu Si, Filippo De Lillo, Guido Boffetta +1
In turbulent flows, energy flux refers to the transfer of kinetic energy across different scales of motion, a concept that is a cornerstone of turbulence theory. The direction of n…
