Splitting of Resonant Frequencies of Acoustic Waves in Rotating Compressible Fluid
It is shown that in a rotating compressible fluid the resonant frequencies (measured in a system of reference rotating together with the medium) for the azimuthally running acoustic waves are split into two components. The received results can be of practical significance as a basis of a method of measurements of angular speed of medium and for acoustics of rotating technical devices.
