    Abstract
  • For the most important flutter problem of turbomachinery blades,the fluid-structure interaction (FSI) problems and flutter characteristic of turbomachinery blades were studied in present paper based on the CFD/CSD (computational fluid dynamics/computational structural dynamics) algorithm.The three-dimensional unsteady Navier-Stokes equations and three-dimensional structural model were solved by the finite volume method and the finite element method,respectively.High accuracy in calculation and data exchange were gained by using load transfer,deformation tracking and synchronization between two solvers.The procedure successfully simulated the aeroelastic responses of a high performance fan rotor,NASA (National Aeronautics and Space Administration) Rotor 67,under a range of operational conditions,and the results were compared with the experiment.The results show that the flutter mechanics of the compressor blade could be illustrated based on the distribution of cycle work and mean pressure,which is helpful to the decision of compressor stability.
