Fluctuation Relations at Large Scales in Three-Dimensional Hydrodynamic Turbulence
Alexandros Alexakis, Sergio Chibbaro, Guillaume Michel
It has long been conjectured that, in three dimensional turbulence, velocity modes at scales larger than the forcing scale follow equilibrium dynamics. Recent numerical and experim…
Heat-flux Fluctuations reveals regime transitions in Rayleigh-Bénard convection
Vincent Labarre, Stéphan Fauve, Sergio Chibbaro
The study of the transitions among different regimes in thermal convection has been an issue of paramount importance in fluid mechanics. While the bifurcations at low Rayleigh numb…
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…
