Band-Ensemble Spectral Proper Orthogonal Decomposition with Frequency Attribution
Jakob G. R. von Saldern, Oliver T. Schmidt, Philipp Godbersen +2
This study presents band-ensemble Spectral Proper Orthogonal Decomposition (bSPOD). The approach is inspired by frequency smoothing, a method used to reduce estimator variance in p…

Spectral analysis of attached and separated turbulent flows over a Gaussian-shaped bump
Roman Klopsch, Lukas M. Fuchs, Georgios Rigas +2
We investigate the broadband turbulent dynamics of attached and separated flows over a Gaussian bump, focusing on the origin of low-frequency coherent structures. The analysis comb…
