Suppression of Rayleigh-Taylor turbulence by time-periodic acceleration
G. Boffetta, M. Magnani, S. Musacchio
The dynamics of Rayleigh-Taylor turbulence convection in presence of an alternating, time periodic acceleration is studied by means of extensive direct numerical simulations of the…
Measuring surface gravity waves using a Kinect sensor
F. Toselli, F. De Lillo, M. Onorato +1
We present a technique for measuring the two-dimensional surface water wave elevation both in space and time based on the low-cost Microsoft Kinect sensor. We discuss the capabilit…
Phase transition to large scale coherent structures in 2d active matter turbulence
Moritz Linkmann, Guido Boffetta, M. Cristina Marchetti +1
The collective motion of microswimmers in suspensions induce patterns of vortices on scales that are much larger than the characteristic size of a microswimmer, attaining a state c…
Rayleigh-Taylor turbulence with singular nonuniform initial conditions
Luca Biferale, Guido Boffetta, Alexei A. Mailybaev +1
We perform direct numerical simulations of three dimensional Rayleigh-Taylor turbulence with a nonuniform singular initial temperature background. In such conditions, the mixing la…
Time irreversibility in reversible shell models of turbulence
Massimo De Pietro, Luca Biferale, Guido Boffetta +1
Turbulent flows governed by the Navier-Stokes equations (NSE) generate an out-of-equilibrium time irreversible energy cascade from large to small scales. In the NSE, the energy tra…
