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…
Gyrotactic swimmers in turbulence: shape effects and role of the large-scale flow
Matteo Borgnino, Guido Boffetta, Filippo De Lillo +1
We study the dynamics and the statistics of dilute suspensions of gyrotactic swimmers, a model for many aquatic motile microorganisms. By means of extensive numerical simulations o…
Cyclone-anticyclone asymmetry in rotating thin fluid layers
G. Boffetta, F. Toselli, M. Manfrin +1
We report of a series of laboratory experiments and numerical simulations of freely-decaying rotating turbulent flows confined in domains with variable height. We show that the ver…
Drag enhancement in a dusty Kolmogorov flow
A. Sozza, M. Cencini, S. Musacchio +1
Particles suspended in a fluid exert feedback forces that can significantly impact the flow, altering the turbulent drag and velocity fluctuations. We study flow modulation induced…
Conformal invariance of weakly compressible two-dimensional turbulence
Leonardo Puggioni, Alexei G. Kritsuk, Stefano Musacchio +1
We study conformal invariance of vorticity clusters in weakly compressible two-dimensional turbulence at low Mach numbers. On the basis of very high resolution direct numerical sim…
