摘要:
This article provides theoretical results for the acoustic power output from point sources moving with an arbitrary subsonic speed along a general trajectory. Applications to steady and nonsteady rotational motions and to rectilinear and elliptical motions are presented. A harmonic analysis of the power output from one or more point sources in steady rotational motion is given, which includes an account of the distribution among individual modes at different speeds.
