We report the interaction between active non-spherical swimmers and a long-standing flow
structure, Lagrangian coherent structures (LCSs), in a weakly turbulent two-dimensional …

Turbulence in two-dimensional flows is expected to produce a dynamical state in which
energy condenses into the largest scale allowed by the system when the scale at which …

Tidal currents are predominant in coastal areas, causing the generation of vortices at
different scales. We reproduce the main process of vortex shedding generated in tidal …

We apply a coarse-graining technique to understand the efficiency of scale-to-scale
transport of energy and enstrophy in a quasi-two-dimensional weakly turbulent periodic flow …

What is the most robust way to communicate flow trajectories? To answer this question, we
employ two neural networks to respectively deconstruct (the encoder) and reconstruct (the …

Recently, advances in techniques for the detection of Lagrangian coherent structures (LCSs)
have driven forward understanding of kinematics and particle transport in a variety of flows …

Complex dynamical systems can potentially contain a vast amount of information. Accurately
assessing how much of this information must be captured to retain the essential physics is a …

This Note discusses a connection between deterministic Lagrangian coherent structures
(robust fluid parcels which move coherently in unsteady fluid flows according to a …
