The analysis of dependences for the estimation of centrifugal blad's machines noise

Abstract

The analysis of dependences of an estimation of a level of the sound power, offered by various authors, with reference to two inlet radial fans and to one-stage radial compressors with blade's diffuser is given. The new formula for an estimation of a level of the sound power, taking into account, as aerodynamic characteristics, so geometrical parameters of radial machines is offered.
