Thermal behaviour of settling heavy inertial particles in turbulent natural convection
Hamid Reza Zandi Pour, Guido Boffetta, Stefano Musacchio +1
We investigate the dynamical and thermal behaviour of settling heavy inertial particles in bulk turbulent thermal convection. Direct numerical simulations are performed in a homoge…
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…
Growth of small localized perturbations in Surface Quasi-Geostrophic turbulence
V. J. Valadão, M. Cencini, F. De Lillo +2
The butterfly effect, namely the amplification of an initially localized infinitesimal perturbation, is a fundamental hallmark of chaotic systems. While this phenomenon is well und…
A new form of mixing in turbulent sedimentation
Simone Tandurella, Marco Edoardo Rosti, Stefano Musacchio +1
We study the sedimentation of finite-size inertial particles in a Rayleigh-Taylor-like setup using state-of-the-art direct numerical simulations. The falling particles are observed…
Lagrangian chaos and the enstrophy cascade in Ekman-Navier-Stokes two-dimensional turbulence
Francesco Michele Ventrella, Victor de Jesus Valadão, Guido Boffetta +2
Two-dimensional turbulence with linear (Ekman) friction exhibits spectral properties that deviate from the classical Kraichnan prediction for the direct enstrophy cascade. In parti…
Transition to the buoyancy dominated regime in a planar temporal forced plume
G. Boga, A. Cimarelli, M. Crialesi Esposito +3
We study the transition from momentum- to buoyancy-dominated regime in temporal jets forced by gravity. From the conservation of the thermal content and of the volume flux, we deve…
