An analysis of acoustic wave radiation conditions within the structural system of an axial dynamic generator
This paper analysis radiation conditions of an acoustic wave in an axial generator with outlets of the stator entering a common horn with a ring-shaped cross section. Acoustic properties of the generator horn, including the wave reflected from the outlet, were considered. The influence of the impedance misfit in the outlets of stater openings-horn inlet system, on the acoustic power emission was estimated. A theoretical and experimental analysis was performed in order to determine the influence of a finite horn length on the power emission and generator efficiency.
