Aeroacoustic analysis using natural Helmholtz–Hodge decomposition
Journal of Sensors and Sensor Systems
<p><strong>Abstract.</strong> The analysis of aeroacoustic phenomena is crucial for a deeper understanding of the damping mechanisms of a sound-absorbing bias flow liner (BFL). For this purpose, simultaneous measurements of the sound field and the flow field in a BFL are required. The fluid velocity can serve as the measurand, where both the acoustic particle velocity and the aerodynamic flow velocity contribute and, thus, can be acquired simultaneously. However, there is a need to separatedoi:10.5194/jsss-7-113-2018 fatcat:astqxyle6fhq3gxtnjf4pi3yz4
