Abstract

A numerical simulation method for fluid-structure interaction (FSI) in compressor was presented to predict the aeroelastic stability of blade.Results from steady-state computation were compared with time-averaged experimental data in this paper.On the basis of the steady-state simulation

a flow solver was coupled to a structure solver by using a fluid-structure interface method.The integration of the three-dimensional unsteady Navier-Stokes (N-S) equations was performed in time domain

simultaneously to the integration of a three-dimensional structure model.In the process of coupling

energy transferred from physical interface between fluid and structure.The study shows that the developed fluid-structure method is feasible to predict the aeroelastic stability of blades.The result of numerical simulation shows the response of blade

thus helping to predict the flutter.
