In this paper we study the statistical laws of relative dispersion in two-dimensional
turbulence by deriving an exact equation governing its evolution in time, then evaluating the …

The relative dispersion of fluid particle pairs in isotropic turbulence is studied using direct
numerical simulation, in greater detail and covering a wider Reynolds number range than …

We investigate Lagrangian relative dispersion in direct numerical simulation of two-
dimensional inverse cascade turbulence. The analysis is performed by using both standard …

Relative dispersion in fully developed turbulence is investigated by means of direct
numerical simulations. Lagrangian statistics is found to be compatible with Richardson …

The single-particle dispersion, Lagrangian structure functions and Lagrangian energy
spectra characteristic of two-dimensional incompressible turbulent flows are investigated …

We discuss a series of numerical experiments on the dispersion of neutrally buoyant
particles in two-dimensional turbulent flows. The topology of two-dimensional turbulence is …

Two-dimensional isotropic turbulence is investigated in its development from an arbitrarily
specified initial flow through its transformation into a statistically self-preserving decaying …

A simple two-point closure scheme for homogeneous axisymmetric turbulence is developed.
For the isotropic case it is essentially an eddy-viscosity assumption in real space for the …

The statistical properties of turbulent fluids depend on how local the energy transfers among
scales are, ie whether the energy transfer at some given scale is due to the eddies at that …

We study the spectral statistics of the fluctuations of a passive scalar convected by a two-
dimensional homogeneous isotropic turbulence using the eddy-damped quasinormal …
