Statistics of the velocity gradient tensor perceived by a set of four tracer particles in homogeneous rotating turbulence

Résumé

The dynamics and structure of rotating homogeneous turbulence is investigated through the statistical properties of the “perceived” velocity gradient tensor, defined by interpolation from the locations and velocities of a set of four particles. Results from direct numerical simulations of forced homogeneous rotating turbulence at different Rossby numbers are presented. We thus provide a multi-scale analysis of the dynamics of rotating turbulence, and of some of its important features.
