Enhancing Aeroacoustic Wind Tunnel Studies through Massive Channel Upscaling with MEMS Microphones
Daniel Ernst, Armin Goudarzi, Reinhard Geisler +3
This paper presents a large 6~m x 3~m aperture 7200 MEMS microphone array. The array is designed so that sub-arrays with optimized point spread functions can be used for beamformin…
XaaS: Acceleration as a Service to Enable Productive High-Performance Cloud Computing
Torsten Hoefler, Marcin Copik, Pete Beckman +8
HPC and Cloud have evolved independently, specializing their innovations into performance or productivity. Acceleration as a Service (XaaS) is a recipe to empower both fields with…
Aeroacoustic testing on a full aircraft model at high Reynolds numbers in the European Transonic Windtunnel
Thomas Ahlefeldt, Daniel Ernst, Armin Goudarzi +2
This paper presents an end-to-end approach for the assessment of pressurized and cryogenic wind tunnel measurements of an EMBRAER scaled full model close to real-world Reynolds num…
Beamforming for measurements under disturbed propagation conditions using numerically calculated Green's functions
Marius Lehmann, Daniel Ernst, Marc Schneider +2
Beamforming methods for sound source localization are usually based on free-field Green's functions to model the sound propagation between source and microphone. This assumption is…
Weighted Data Spaces for Correlation-Based Array Imaging in Experimental Aeroacoustics
Hans-Georg Raumer, Carsten Spehr, Thorsten Hohage +1
This article discusses aeroacoustic imaging methods based on correlation measurements in the frequency domain. Standard methods in this field assume that the estimated correlation…
