Численное исследование аэроупругого поведения компрессорной ступени в трехмерном потоке вязкого газа

Abstract

The partial integration method of the solution for the coupled problem of unsteady aerodynamics and elastic blades oscillations has been applied to simulate the aeroelastic behaviour of compressor stage. The three-dimensional unsteady viscous gas flow is written by Reynolds averaged Navier-Stokes equations. The dynamic analysis uses the modal approach. The amplitude-frequency characteristics of the unsteady loads and blades elastic oscillations have been presente
