Physical arguments are followed by mathematical developments to show how aerodynamic sound is generated as a result of the movement of vortices, or of vorticity, in an unsteady fluid flow.

In this book we shall consider principally the production of sound by un- steady motions of a fluid. Any fluid that possesses intrinsic kinetic energy, that is ...
Abstract. The theory of vortex sound is introduced. From Lighthill's acoustic analogy, it is shown how vorticity and entropy fluctuations can be seen as sources ...
Vortex motion is the only source of aerodynamic sound production in low Mach number flow: the unsteady part of the vorticity distribution contributes linearly ...
A conservative form of the vortex sound theory is obtained by reiterating the assumptions of conservation of these flow invariants. This alternative form of the ...
The discussion deals specifically with low Mach number flows, which enables the sound produced by 'vortex-surface' interactions to be analysed using the ' ...
