The real butterfly effect: from the pop culture to mathematics and physics
Victor de Jesus Valadão, Erik Aurell, Guido Boffetta +3
The "butterfly effect", introduced over half a century ago by Edward Lorenz, has shifted from a cornerstone of dynamical systems to a popular metaphor, yet its true physical manife…
Effects of polymer additives on Rayleigh-Taylor turbulence
G. Boffetta, A. Mazzino, S. Musacchio
The role of polymers additives on the turbulent convective flow of a Rayleigh--Taylor system is investigated by means of direct numerical simulations (DNS) of Oldroyd-B viscoelasti…
Statistics of mixing in three-dimensional Rayleigh--Taylor turbulence at low Atwood number and Prandtl number one
G. Boffetta, A. Mazzino, S. Musacchio +1
Three-dimensional miscible Rayleigh--Taylor (RT) turbulence at small Atwood number and at Prandtl number one is investigated by means of high resolution direct numerical simulation…
An update on the double cascade scenario in two-dimensional turbulence
G. Boffetta, S. Musacchio
Statistical features of homogeneous, isotropic, two-dimensional turbulence is discussed on the basis of a set of direct numerical simulations up to the unprecedented resolution $32…
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…
Nonlinear diffusion model for Rayleigh-Taylor mixing
G. Boffetta, F. De Lillo, S. Musacchio
The complex evolution of turbulent mixing in Rayleigh-Taylor convection is studied in terms of eddy diffusiviy models for the mean temperature profile. It is found that a non-linea…
