Numerical Simulation of Aerodynamic Noise Generated by High Speed Trains
Engineering Applications of Computational Fluid Mechanics, 2012 Aerodynamic noise becomes more and more significant and sometimes could be predominant as the running speed of high speed trains increases. As a result, aerodynamic noise has to be taken into consideration during the design of high speed trains.

Aerodynamic Noise and the Estimation of Noise in Aircraft
The Journal of the Acoustical Society of America, 1952Noise resulting from the flow of air over the fuselage of an airplane has been investigated and found to depend principally on approximately the fifth power of the indicated air speed. The resulting emperical relation of noise level to airspeed is found to be quite useful in estimating the noise in the frequency range above 600 cps, for airplanes ...

Journal of Fluid Mechanics, 1971
A symposium on aerodynamic noise was held at Loughborough University from 14 to 17 September 1970 under the sponsorship of the Royal Aeronautical Society and the British Acoustical Society. The objective of the meeting was to focus attention on unsolved theoretical and experimental problems which will require attention over the next few years.

Aerodynamics and Noise of Coaxial Jets
AIAA Journal, 1977The objective of this investigation was to develop a unified prediction method for estimating the aerodynamic and noise characteristics of jets issuing from nozzles of arbitrary geometric shapes. The method has been developed and demonstrated for dual-flow coaxial jets.

On the scattering of aerodynamic noise
Journal of Fluid Mechanics, 1971According to the Lighthill acoustic analogy, the sound induced by a region of turbulence is the same as that due to an equivalent distribution of quadrupole sources within the fluid. It is known that the presence of scattering bodies situated near such multipoles can convert some of their intense near field energy into the form of sound waves whose ...

Aerodynamic Noise produced by a Gliding Owl
Nature, 1971THE flight of owls has been reported by ornithologists to be unusually quiet1. This conclusion is generally based on the success of the owl's hunting technique and on the relative inability of the observer to distinguish the owl aurally from other birds.
