title: An exact frequency-domain solution of the sound radiated from the rotating dipole point source.
abstract: An exact solution of the acoustic field around the rotating dipole source has been derived by using a series expansion method and the gradient calculation in the spherical and cylindrical coordinate systems which extends a previously published solution for a rotating monopole source. The proposed exact solution establishes an analytical method to predict the sound radiated from the rotating blades once the acoustic sources have been known.
