Sound propagation from a simple source in a wind tunnel
John E. Cole · NASA STI Repository (National Aeronautics and Space Administration) · 1975
The nature of the acoustic field of a simple source in a wind tunnel under flow conditions was examined theoretically and experimentally. The motivation of the study was to establish aspects of the theoretical framework for interpreting acoustic data taken (in wind) tunnels using in wind microphones. Three distinct investigations were performed and are described in detail.
