Dynamical scaling and intermittency in shell models of turbulence
R. Benzi, L. Biferale, M. Sbragaglia
We introduce a model for the turbulent energy cascade aimed at studying the effect of dynamical scaling on intermittency. In particular, we show that by slowing down the energy tra…
A lattice Boltzmann study of non-hydrodynamic effects in shell models of turbulence
R. Benzi, L. Biferale, M. Sbragaglia +2
A lattice Boltzmann scheme simulating the dynamics of shell models of turbulence is developed. The influence of high order kinetic modes (ghosts) on the dissipative properties of t…
Anisotropy in Turbulent Flows and in Turbulent Transport
Luca Biferale, Itamar Procaccia
We discuss the problem of anisotropy and intermittency in statistical theory of high Reynolds-number turbulence (and turbulent transport). We present a detailed description of the…
Multifractal statistics of Lagrangian velocity and acceleration in turbulence
L. Biferale, G. Boffetta, A. Celani +3
The statistical properties of velocity and acceleration fields along the trajectories of fluid particles transported by a fully developed turbulent flow are investigated by means o…
Anisotropic fluctuations in turbulent sheared flows
Boris Jacob, Luca Biferale, Gaetano Iugo +1
An experimental analysis of small-scales anisotropic turbulent fluctuations has been performed in two different flows. We analyzed anisotropic properties of an homogeneous shear fl…
Lagrangian statistics in fully developed turbulence
L. Biferale, G. Boffetta, A. Celani +2
The statistical properties of fluid particles transported by a fully developed turbulent flow are investigated by means of high resolution direct numerical simulations. Single traj…
Anomalous scaling and universality in hydrodynamic systems with power-law forcing
L. Biferale, M. Cencini, A. S. Lanotte +2
The problem of the interplay between normal and anomalous scaling in turbulent systems stirred by a random forcing with a power law spectrum is addressed. We consider both linear a…
