Abstract
In the realm of aeroacoustic applications, precise and detailed analysis of acoustic phenomena is essential for enhancing the comprehension of aerodynamic sound emission mechanisms and the design and performance of aerodynamic devices and systems, such as wings and engines. In this particular context, beamforming is currently receiving significant attention within the scientific community due to its ability to distinguish and measure acoustic sources through the use of phased arrays. This study proposes the development of an innovative UI-based beamforming tool implementing the Generalized Inverse Beamforming (GIBF) technique, which is a promising method resolving coherent and incoherent sparse source distributions that especially occur in aerodynamics.
This approach is designed to enable accurate and reliable measurements both in physical wind tunnels and Computational AeroAcoustics (CAA) simulations
