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…

Standing-Wave Dynamics in Low-Frequency Breathing of a Turbulent Separation Bubble
Lukas M. Fuchs, Ben Steinfurth, Jakob G. R. von Saldern +2
This study investigates the low-frequency dynamics of a turbulent separation bubble (TSB) over a backward-facing ramp, with a focus on large-scale coherent structures associated wi…
