    Classical flutter analysis of low pressure steam turbine blade cascade using 3D boundary element method

  • Original language description

    In this paper study of aeroelastic stability in steam turbine rotor is carried out using boundary element method. A mesh free fluidnsolver is developed for fast estimation of unsteady aerodynamic loading and to estimate the aerodynamic damping in 3D blade cascade. The aerodynamic damping is estimated in traveling wave mode. The unsteady incompressible flow field is modeled using 3D surface Panel method. The proposed methodology successfully estimates aerodynamic damping with acceptable accuracy the for the aeroelastic (classical n flutter) analysis of 3D blade cascade. The simulated results are compared with experimental data. The simulated aerodynamic damping shows good agreement withnexperimental results. The present methodology shows significant reduction in computational time over computational fluid dynamic solvers.
