A route to thermalization in the -Fermi-Pasta-Ulam system
Miguel Onorato, Lara Vozella, Davide Proment +1
We study the original -Fermi-Pasta-Ulam (FPU) system with and masses connected by a nonlinear quadratic spring. Our approach is based on resonant wave-wave intera…
Polymer heat transport enhancement in thermal convection: the case of Rayleigh-Taylor turbulence
G. Boffetta, A. Mazzino, S. Musacchio +1
We study the effects of polymer additives on turbulence generated by the ubiquitous Rayleigh-Taylor instability. Numerical simulations of complete viscoelastic models provide clear…
Kolmogorov scaling and intermittency in Rayleigh-Taylor turbulence
G. Boffetta, A. Mazzino, S. Musacchio +1
The Rayleigh--Taylor (RT) turbulence is investigated by means of high resolution numerical simulations. The main question addressed here is on whether RT phenomenology can be consi…
Phase-field model for the Rayleigh--Taylor instability of immiscible fluids
Antonio Celani, Andrea Mazzino, Paolo Muratore-Ginanneschi +1
The Rayleigh--Taylor instability of two immiscible fluids in the limit of small Atwood numbers is studied by means of a phase-field description. In this method the sharp fluid inte…
Rayleigh--Taylor turbulence in two dimensions
Antonio Celani, Andrea Mazzino, Lara Vozella
The first consistent phenomenological theory for two and three dimensional Rayleigh--Taylor (RT) turbulence has recently been presented by Chertkov [Phys. Rev. Lett. {\bf 91} 11500…
