Two-particle dispersion is of central importance to a wide range of natural and industrial
applications. It has been an active area of research since seminal paper. This review …

The dynamics of heavy particles suspended in turbulent flows is of fundamental importance
for a wide range of questions in astrophysics, atmospheric physics, oceanography, and …

Chaos: from simple models to complex systems aims to guide science and engineering
students through chaos and nonlinear dynamics from classical examples to the most recent …

The control of matter motion at liquid–gas interfaces opens an opportunity to create two-
dimensional materials with remotely tunable properties. In analogy with optical lattices used …

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 report on an experimental study in which Lagrangian tracking is applied to millions of
microscopic particles floating on the free surface of turbulent water. We leverage a large jet …

Clusters of material at the ocean surface have been frequently observed. Such
accumulations of material play an important role in a variety of applications, from biology to …

The small-scale velocity gradient is connected to fundamental properties of turbulence at the
large scales. By neglecting the viscous and non-local pressure Hessian terms, we derive a …

We study the free surface of a turbulent flow, in particular the relation between the statistical
properties of the wrinkled surface and those of the velocity field beneath it. Channel flow …

Turbulent flows at the surface of the ocean deviate from geostrophic equilibrium on scales
smaller than about 10 km. These scales are associated with important vertical transport of …
