Geometry and violent events in turbulent pair dispersion
Rehab Bitane, Holger Homann, Jeremie Bec
The statistics of Lagrangian pair dispersion in a homogeneous isotropic flow is investigated by means of direct numerical simulations. The focus is on deviations from Richardson ed…
Timescales of Turbulent Relative Dispersion
Rehab Bitane, Jérémie Bec, Holger Homann
Tracers in a turbulent flow separate according to the celebrated Richardson--Obukhov law, which is usually explained by a scale-dependent effective diffusivity. Here, sup…
Mass fluctuations and diffusion in time-dependent random environments
Giorgio Krstulovic, Rehab Bitane, Jeremie Bec
A mass ejection model in a time-dependent random environment with both temporal and spatial correlations is introduced. When the environment has a finite correlation length, indivi…
Kolmogorov-Sinai entropy in field line diffusion by anisotropic magnetic turbulence
Alexander V. Milovanov, Rehab Bitane, Gaetano Zimbardo
The Kolmogorov-Sinai (KS) entropy in turbulent diffusion of magnetic field lines is analyzed on the basis of a numerical simulation model and theoretical investigations. In the par…
