We present a collection of eight data sets from state-of-the-art experiments and numerical simulations on turbulent velocity statistics along particle trajectories obtained in different flows withâ€¦ (More)

The numerical study of physical problems often require integrating the dynamics of a large number of particles evolving according to a given set of equations. Particles are characterized by theâ€¦ (More)

We present results from consistent dynamo simulations, where the electrically conducting and incompressible flow inside a cylinder vessel is forced by moving impellers numerically implemented by aâ€¦ (More)

Heavy inertial particles transported by a turbulent flow are shown to concentrate in the regions where an advected passive scalar, such as temperature, displays very strong frontlike discontinuities.â€¦ (More)

The dynamics of neutrally buoyant particles transported by a turbulent flow is investigated for spherical particles with radii of the order of the Kolmogorov dissipative scale or larger. Theâ€¦ (More)

We report on a comparison of high-resolution numerical simulations of Lagrangian particles advected by incompressible turbulent hydroand magnetohydrodynamic (MHD) flows. Numerical simulations wereâ€¦ (More)

Studying strongly turbulent flows is still a major challenge in fluid dynamics. It is highly desirable to have comparable experiments to obtain a better understanding of the mechanisms generatingâ€¦ (More)

Tracers in a turbulent flow separate according to the celebrated t3/2 Richardson-Obukhov law, which is usually explained by a scale-dependent effective diffusivity. Here, supported byâ€¦ (More)

We study small-scale and high-frequency turbulent fluctuations in three-dimensional flows under Fourier-mode reduction. TheNavierâ€“Stokes equations are evolved on a restricted set ofmodes, obtained asâ€¦ (More)

Smoluchowski's coagulation kinetics is here shown to fail when the coalescing species are dilute and transported by a turbulent flow. The intermittent Lagrangian motion involves correlated violentâ€¦ (More)
