The Source of Aerodynamic Noise

International Journal of Aeroacoustics, 2003
This paper is a tribute to Alan Powell's achievements and his extensive publications in hydro and aeroacoustics.1 The theory of Aerodynamic Noise was established by Sir James Lighthill in 1952. The beauty of Lighthill's treatment was that he based this theory on the exact Navier-Stokes equations and showed, by their rearrangement, how the source of ...

Experimental evaluation on vehicle aerodynamic noise performance

International Journal of Vehicle Performance, 2018
In this study, a passenger car was tested for its aerodynamic noise performance in terms of sound pressure level in the wind tunnel at Tongji University (Shanghai Automotive Wind Tunnel Center), where the phase microphone array was used along with sound surface microphones and artificial heads combining with the adhesive tape sealing method.

Further Topics in Aerodynamic Noise

2012
In principle, the convected quadrupole theory, as developed by Ffowcs-Williams, can be used also for supersonic jet noise. However, subsonic jet noise, where no complex phenomena such as shock or screeching noise exist, is based mainly on turbulent mixing.

AERODYNAMIC NOISE: A CRITICAL SURVEY

Journal of Sound and Vibration, 2000
Annoyance due to railway noise is a particularly sensitive aspect of new high-speed projects. Many studies have shown that aerodynamic noise becomes significant above 300 km/h and can become predominant with the reduction of the contribution of rolling noise.

A SURVEY OF AERODYNAMIC NOISE

1964
Abstract : A representative survey of the literature of aerodynamic noise was made. This was not intended to be an exhaustive list but rather to give the state of the field presently. It was found that much of the research done in this field is either experimental or semi-empirical.
