We present a detailed investigation of the particle pair separation process in homogeneous
isotropic turbulence. We use data from direct numerical simulations up to R λ∼ 280 …

The relative diffusion of fluid particle pairs in statistically stationary isotropic turbulence is
studied by direct numerical simulation, at a Taylor‐scale Reynolds number of about 90. The …

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 the Richardson …

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 statistics of Lagrangian particles transported by a three-dimensional fully developed
turbulent flow is investigated by means of high-resolution direct numerical simulations. The …

The mixing properties of turbulent flows are, at first order, related to the dynamics of
separation of particle pairs. Scaling laws for the evolution in time of the mean distance …

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 demonstrate that kinematic simulation (KS) of three-dimensional homogeneous
turbulence produces fluid element pair statistics in agreement with the predictions of L F …

Results from direct numerical simulations (DNS) of particle relative dispersion in three-
dimensional homogeneous and isotropic turbulence at Reynolds number. The right tail of …

We study the statistics of pair dispersion in two-dimensional turbulence. Direct numerical
simulations show that the probability distribution function (pdf) of pair separations is in …
