Effects of anisotropy on the geometry of tracer particle trajectories in turbulent flows
Yasmin Hengster, Martin Lellep, Julian Weigel +9
Using curvature and torsion to describe Lagrangian trajectories gives a full description of these as well as an insight into small and large time scales as temporal derivatives up…
Defining Coherent Vortices Objectively from the Vorticity
George Haller, Alireza Hadjighasem, Mohammad Farazmand +1
Rotationally coherent Lagrangian vortices are formed by tubes of deforming fluid elements that complete equal bulk material rotation relative to the mean rotation of the deforming…
Atmospheric rivers as Lagrangian coherent structures
Daniel Garaboa, Jorge Eiras-Barca, Florian Huhn +1
We show that filamentous Atmospheric Rivers (ARs) over the Northern Atlantic Ocean are closely linked to attracting Lagrangian Coherent Structures (LCSs) in the large scale wind fi…
LCS Tool : A Computational Platform for Lagrangian Coherent Structures
K. Onu, F. Huhn, G. Haller
We give an algorithmic introduction to Lagrangian coherent structures (LCSs) using a newly developed computational engine, LCS Tool. LCSs are most repelling, attracting and shearin…
Automated detection of coherent Lagrangian vortices in two-dimensional unsteady flows
Daniel Karrasch, Florian Huhn, George Haller
Coherent boundaries of Lagrangian vortices in fluid flows have recently been identified as closed orbits of line fields associated with the Cauchy-Green strain tensor. Here we deve…
Large spiral and target waves: Turbulent diffusion boosts scales of pattern formation
A. von Kameke, F. Huhn, A. P. Muñuzuri +1
In absence of advection, reaction-diffusion systems are able to organize into spatiotemporal patterns, in particular spiral and target waves. Whenever advection is present and can…
