The Lagrangian description of turbulence is characterized by a unique conceptual simplicity
and by an immediate connection with the physics of dispersion and mixing. In this article, we …

Particle tracking is a competitive technique widely used in two-phase flows and best suited
to simulate the dispersion of heavy particles in the atmosphere. Most Lagrangian models in …

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 …

We report experimental results on the motion of tracer and non-tracer particles in intense
turbulent water flows between counter-rotating disks measured by three-dimensional …

The dynamics of particles in turbulence when the particle size is larger than the dissipative
scale of the carrier flow are studied. Recent experiments have highlighted signatures of …

Preventive measures to reduce infection are needed to combat the COVID-19 pandemic and
prepare for a possible endemic phase. Current prophylactic vaccines are highly effective to …

Using two-point velocity and position data from the near-simultaneous release of O (100)
GPS-tracked surface drifters in the northern Gulf of Mexico, we examine the applicability of …

We present a study of Eulerian and Lagrangian statistics from a high-resolution numerical
simulation of isotropic and homogeneous turbulence using the FLASH code, with an …

A recently developed public turbulence database system (http://turbulence. pha. jhu. edu)
provides new ways to access large datasets generated from high-performance computer …

The statistics of the velocity gradient tensor in turbulent flows is of both theoretical and
practical importance. The Lagrangian view provides a privileged perspective for studying the …
