Typical fluid particle trajectories are sensitive to changes in their initial conditions. This
makes the assessment of flow models and observations from individual tracer samples …

There has been a proliferation in the development of Lagrangian analytical methods for
detecting coherent structures in fluid flow transport, yielding a variety of qualitatively different …

We use a three-dimensional computational model to study the fluid transport and mixing due
to the beating of an infinite array of cilia. In accord with recent experiments, we observe two …

Groundwater plumes originating from continuously emitting sources are typically controlled
by transverse mixing between the plume and reactants in the ambient solution. In two …

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 phenomenon of chaotic advection mixing in laminar stirred tanks, particularly when
handling high-viscosity fluids, represents a common and challenging issue in various …

Many complex flows such as those arising from the collective motion of ocean plastics in
geophysics or motile cells in biology are characterized by sparse and noisy trajectory …

This work reports the formation and characterization of antipleptic and symplectic
metachronal waves in 3D cilium arrays immersed in a two-fluid environment, with a viscosity …

Characterizing the topology of three‐dimensional steady‐state flow fields is useful to
describe the physical processes controlling the deformation of solute plumes and …

Mixing and coherence are essential topics for understanding and describing transport in
fluid dynamics and other nonautonomous dynamical systems. Only recently has the idea of …
