We report recent results from a high-resolution numerical study of fluid particles transported
by a fully developed turbulent flow. Single-particle trajectories were followed for a time range …

A numerical study of turbulence seeded with light particles is presented. We analyze the
statistical properties of coherent, small-scale structures by looking at the trapping events of …

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 …

We present the results of direct numerical simulations (DNS) of turbulent flows seeded with
millions of passive inertial particles. The maximum Reynolds number is Re λ∼ 200. We …

We study the dynamics of neutrally buoyant particles with diameters varying in the range [1,
45] in Kolmogorov scale units (η) and Reynolds numbers based on Taylor scale (Reλ) …

A study is performed using direct numerical simulation to examine the effect of turbulence on
particle dispersion in a columnar vortex. A procedure is used to generate initial conditions in …

We investigate experimentally the spatial distributions of heavy and neutrally buoyant
particles of finite size in a fully turbulent flow. Because their Stokes number (ie, the ratio of …
