ABSTRAKT

A mathematical model is presented for the calculation of the multistage turbomachinery tonal noise that takes into account the effects of the unsteady aerodynamic interaction in a system of several mutually rotating blade rows. The model is based on the frequency/modal spectrum analysis of turbomachinery gas flow parameter fluctuations, which allows determining the space/time structure of the perturbation field induced by the interaction of the rotor and stator blade rows. The method of tonal noise calculation is realized in the CIAM domestic three-dimensional acoustics solver (3DAS) using modern highly efficient finite-difference schemes of the numerical integration of the Euler equations for flow parameter fluctuations.
