Fast estimation of classical flutter stability of turbine blade by reduced CFD modelling
Original language description
The paper presents a medium fidelity reduced ordered numerical model for the calculation of aeroelastic stability diagram of 3D blade cascade of low pressure stage of steam turbine. The aeroelastic stability in steam turbine blades are calculated for the classical flutter problem. The calculation of the stability diagram for the problem of classical flutter is evaluated with assumption of running waves. Running waves will be simulated by the inter-blade phase shift approach between the blades in the cascade. Panel method based boundary element type flow solver is employed for calculation of unsteady aerodynamic forces and model the flow flied. This method is good compromise of speed and accuracy for the estimation of the stability of the blades on a classical flutter. The estimated results are compared with experimental and the high fidelity computational fluid dynamic model data.
