Detection of evolving Lagrangian coherent structures: A multiple object tracking approach
Theodore MacMillan, Nicholas T. Ouellette, David H. Richter · Physical Review Fluids · 2020
During the course of a complex flow, many coherent structures may be created and destroyed. Here, tools from object tracking in video analysis are used to dynamically track these transient coherent structures, allowing for coherence timescales to be considered independently of the overall flow timescale and revealing the inner dynamics of the structures themselves.
