Efficient global resolvent analysis via the one-way Navier-Stokes equations. Part 2. Optimal response
Georgios Rigas, Omar Kamal, Aaron Towne +1
In this study, we develop an efficient approach for approximating resolvent modes via spatial marching. Building on the methodology from Part 1, we leverage the ability of the proj…
Efficient global resolvent analysis via the one-way Navier-Stokes equations. Part 1. Forced response
Aaron Towne, Georgios Rigas, Ethan Pickering +1
Resolvent analysis is a powerful tool for modeling and analyzing turbulent flows and in particular provides an approximation of coherent flow structures. Despite recent algorithmic…
Symmetry-Aware Autoencoders: s-PCA and s-nlPCA
Simon Kneer, Taraneh Sayadi, Denis Sipp +2
Nonlinear principal component analysis (NLPCA) via autoencoders has attracted attention in the dynamical systems community due to its larger compression rate when compared to linea…
An empirical mean-field model of symmetry-breaking in a turbulent wake
Jared L. Callaham, Georgios Rigas, Jean-Christophe Loiseau +1
This work develops a low-dimensional nonlinear stochastic model of symmetry-breaking coherent structures from experimental measurements of a turbulent axisymmetric bluff body wake.…
