Intermittency in the relative separations of tracers and of heavy particles in turbulent flows
L. Biferale, A. S. Lanotte, R. Scatamacchia +1
Results from Direct Numerical Simulations of particle relative dispersion in three dimensional homogeneous and isotropic turbulence at Reynolds number are presented.…
Clustering of vertically constrained passive particles in homogeneous, isotropic turbulence
Massimo De Pietro, Michel A. T. van Hinsberg, Luca Biferale +3
We analyze the dynamics of small particles vertically confined, by means of a linear restoring force, to move within a horizontal fluid slab in a three-dimensional (3D) homogeneous…
Deformation statistics of sub-Kolmogorov-scale ellipsoidal neutrally buoyant drops in isotropic turbulence
Luca Biferale, Charles Meneveau, Roberto Verzicco
Small droplets in turbulent flows can undergo highly variable deformations and orientational dynamics. For neutrally buoyant droplets smaller than the Kolmogorov scale, the dominan…
Numerical simulations of aggregate breakup in bounded and unbounded turbulent flows
Matthaus U. Babler, Luca Biferale, Luca Brandt +8
Breakup of small aggregates in fully developed turbulence is studied by means of direct numerical simulations in a series of typical bounded and unbounded flow configurations, such…
Evolution of a double-front Rayleigh-Taylor system using a GPU-based high resolution thermal Lattice-Boltzmann model
P. Ripesi, L. Biferale, S. F. Schifano +1
We study the turbulent evolution originated from a system subjected to a Rayleigh-Taylor instability with a double density at high resolution in a 2 dimensional geometry using a hi…
Natural convection with mixed insulating and conducting boundary conditions: low and high Rayleigh numbers regimes
P. Ripesi, L. Biferale, M. Sbragaglia +1
We investigate the stability and dynamics of natural convection in two dimensions, subject to inhomogeneous boundary conditions. In particular, we consider a Rayleigh-Bènard (RB) c…
A new assessment of the second order moment of Lagrangian velocity increments in turbulence
Alessandra S. Lanotte, Luca Biferale, Guido Boffetta +1
The behavior of the second-order Lagrangian structure functions on state-of-the-art numerical data both in two and three dimensions is studied. On the basis of a phenomenological c…
