Detection of dominant large-scale coherent structures in turbulent pipe flow
Amir Shahirpour, Christoph Egbers, Jörn Sesterhenn
Large-scale coherent structures are identified in turbulent pipe flow at by having long lifetimes, living on large scales and travelling with a certain group velocity. A…

A Characteristic Dynamic Mode Decomposition
Jörn Sesterhenn, Amir Shahirpour
Temporal or spatial structures are readily extracted from complex data by modal decompositions like Proper Orthogonal Decomposition (POD) or Dynamic Mode Decomposition (DMD). Subsp…
