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 …

The motion of fluid particles as they are pushed along erratic trajectories by fluctuating
pressure gradients is fundamental to transport and mixing in turbulence. It is essential in …

We use silicon strip detectors (originally developed for the CLEO III high-energy particle
physics experiment) to measure fluid particle trajectories in turbulence with temporal …

The breakup of drops and bubbles in turbulent fluids is a key mechanism in many
environmental and engineering processes. Even in the well-studied dilute case, quantitative …

The regions associated with high levels of vorticity and energy dissipation are studied in
numerically simulated isotropic turbulence at, with no noticeable dependence on the …

We introduce an original acoustic method to track the motion of tracer particles in high
Reynolds number turbulent flows. We present in detail the experimental technique and show …

The unsteady structure of cavitating flows is investigated by coupled experimental and
numerical means. Experiments focus on the structure and dynamics of sheet cavitation on …

The multiscale effect of cavitation is a complicated multiphase phenomenon involving
macroscale cavities and microscale bubbles. The cavitating flows at four different patterns …

Microbubble-laden homogeneous and isotropic turbulent flow is investigated by using direct
numerical simulation of the three-dimensional Navier–Stokes equations and computing the …

The flow produced in an enclosed cylinder of height-to-radius ratio of two by the counter-
rotation of the top and bottom disks is numerically investigated. When the Reynolds number …
