Non-equilibrium fluctuations of the direct cascade in Surface Quasi Geostrophic turbulence
V. J. Valadão, T. Ceccotti, G. Boffetta +1
We study the temporal fluctuations of the flux of surface potential energy in Surface Quasi-Geostrophic (SQG) turbulence. By means of high-resolution, direct numerical simulations…
Microswimmer trapping in surface waves with shear
Francesco Michele Ventrella, Nimish Pujara, Guido Boffetta +3
Many species of phytoplankton migrate vertically near the surface of the ocean, either in search of light or nutrients. These motile organisms are affected by ocean waves at the su…
Intermittency in turbulent emulsions
Marco Crialesi-Esposito, Guido Boffetta, Luca Brandt +2
We investigate the statistics of turbulence in emulsions of two-immiscible fluids of same density. We compute for the first time velocity increments between points conditioned to b…
Flocking turbulence of microswimmers in confined domains
Leonardo Puggioni, Guido Boffetta, Stefano Musacchio
We extensively study the Toner-Tu-Swift-Hohenberg model of motile active matter by means of direct numerical simulations in a two-dimensional confined domain. By exploring the spac…
Transient inverse energy cascade in free surface turbulence
G. Boffetta, A. Mazzino, S. Musacchio +1
We study the statistics of free-surface turbulence at large Reynolds numbers produced by direct numerical simulations in a fluid layer at different thickness with fixed characteris…
The three-dimensional turbulent cellular flow
S. Berti, G. Boffetta, S. Musacchio
We study, by means of extensive direct numerical simulations, the turbulent flow produced by a two-dimensional cellular forcing in a cubic box with periodic boundary conditions. In…
