Density Field Reconstruction of an Overexpanded Supersonic Jet using Tomographic Background-Oriented Schlieren
Joachim A. Bron, Woutijn J. Baars, Ferdinand F. J. Schrijer
A Tomographic Background-Oriented Schlieren (TBOS) technique is developed to aid in the visualization of compressible flows. An experimental setup was devised around a sub-scale ro…
Low-Frequency Intensity Modulation of High-Frequency Rotor Noise
Woutijn J. Baars, Daniele Ragni
Acoustic spectra of rotor noise yield frequency-distributions of energy within pressure time series. However, they are unable to reveal phase-relations between different frequency…
Opposition flow control for reducing skin-friction drag of a turbulent boundary layer
Giulio Dacome, Robin Mörsch, Marios Kotsonis +1
This work explores the dynamic response of a turbulent boundary layer to large-scale reactive opposition control, at a friction Reynolds number of . A hot-film…
Inner-scaled Helmholtz resonators with grazing turbulent boundary layer flow
Giulio Dacome, Renko Siebols, Woutijn J. Baars
Response details are presented of small-scale Helmholtz resonators excited by grazing turbulent boundary layer flow. A particular focus lies on scaling of the resonance, in relatio…
Reynolds-number scaling of wall-pressure--velocity correlations in wall-bounded turbulence
Woutijn J. Baars, Giulio Dacome, Myoungkyu Lee
Wall-pressure fluctuations are a practically robust input for real-time control systems aimed at modifying wall-bounded turbulence. The scaling behaviour of the wall-pressure--velo…
Quantifying inner-outer interactions in non-canonical wall-bounded flows
Mogeng Li, Woutijn J. Baars, Ivan Marusic +1
We investigate the underlying physics behind the change in amplitude modulation coefficient in non-canonical wall-bounded flows in the framework of the inner-outer interaction mode…
