An inflated dynamic Laplacian to track the emergence and disappearance of semi-material coherent sets
Jason Atnip, Gary Froyland, Péter Koltai
Lagrangian methods continue to stand at the forefront of the analysis of time-dependent dynamical systems. Most Lagrangian methods have criteria that must be fulfilled by trajector…
Persistence and material coherence of a mesoscale ocean eddy
Michael C. Denes, Gary Froyland, Shane R. Keating
Ocean eddies play an important role in the transport and mixing processes of the ocean due to their ability to transport material, heat, salt, and other tracers across large distan…
A Critical Comparison of Lagrangian Methods for Coherent Structure Detection
Alireza Hadjighasem, Mohammad Farazmand, Daniel Blazevski +2
We review and test twelve different approaches to the detection of finite-time coherent material structures in two-dimensional, temporally aperiodic flows. We consider both mathema…
Optimal mixing enhancement
Gary Froyland, Naratip Santitissadeekorn
We introduce a general-purpose method for optimising the mixing rate of advective fluid flows. An existing velocity field is perturbed in a neighborhood to maximize the mixin…
