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…

Identification of structures driving trailing-edge noise. Part II -- Numerical investigation
Zhenyang Yuan, Simon Demange, Kilian Oberleithner +2
The aim of the present work is to investigate the mechanisms of broadband trailing-edge noise generation to improve prediction tools and control strategies. We focus on a NACA 0012…

Identification of structures driving trailing-edge noise. Part I -- Experimental investigation
Simon Demange, Zhenyang Yuan, Simon Jekosch +4
Trailing-edge (TE) noise is the main contributor to the acoustic signature of flows over airfoils. It originates from the interaction of turbulent structures in the airfoil boundar…
