Transport and mixing of scalar quantities in fluid flows is ubiquitous in industry and Nature.
While the more familiar turbulent flows promote efficient transport and mixing by their …

Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension,
societal challenges. In the coming decades, as we strive towards a more sustainable planet …

The Gulf Stream front separates the North Atlantic subtropical and subpolar ocean gyres,
water masses with distinct physical and biogeochemical properties. Exchange across the …

Transport barriers are observed inhibitors of the spread of substances in flows. The
collection of such barriers offers a powerful geometric template that frames the main …

We identify effective carriers of Sargassum in the Caribbean Sea and describe a mechanism
for coastal choking. Revealed from satellite altimetry, the carriers of Sargassum are …

We analyze large-scale patterns in three-dimensional turbulent convection in a horizontally
extended square convection cell by Lagrangian particle trajectories calculated in direct …

Our understanding of the material organization of complex fluid flows has benefited recently
from mathematical developments in the theory of objective coherent structures. These …

The interplay between viscoelasticity and inertia in dilute polymer solutions at high
deformation rates can result in inertioelastic instabilities. The nonlinear evolution of these …

Inertial particles (ie with mass and of finite size) immersed in a fluid in motion are unable to
adapt their velocities to the carrying flow and thus they have been the subject of much …

We carry out assessments of the life cycle of Loop Current vortices, so-called rings, in the
Gulf of Mexico by applying three objective (ie, observer-independent) coherent Lagrangian …
