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 …

The statistical geometry of dispersing Lagrangian clusters of four particles (tetrahedra) is
studied by means of high-resolution direct numerical simulations of three-dimensional …

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 …

Preferential concentration of inertial particles in turbulent flow is studied by high resolution
direct numerical simulations of two-dimensional turbulence. The formation of network-like …

The statistical properties of fluid particles transported by a three-dimensional fully developed
turbulent flow are investigated by means of high resolution direct numerical simulations …

The relative dispersion of pairs of inertial point particles in incompressible, homogeneous
and isotropic three-dimensional turbulence is studied by means of direct numerical …

The objective of the present study is to analyze our recent direct numerical simulation (DNS)
results to explain in some detail the main physical mechanisms responsible for the …

The theory of dispersion of discrete particles by continuous turbulent motions is first
expressed in a 3‐D formalism, as a synthesis between the 1‐D Tchen's theory of dispersion …

Kinematic simulations are non-Markovian Lagrangian models of dispersion that incorporate
turbulentlike flow structure. We investigate the conditions for two-particle dispersion to be …

Our work focuses on the sweep-stick mechanism of particle clustering in turbulent flows
introduced by Chen et al.[L. Chen, S. Goto, and JC Vassilicos,“Turbulent clustering of …
