NUMERICAL ANALYSIS OF FLUTTER INSTABILITY IN SIMPLIFIED BLADE CASCADE
Original language description
In this paper the occurrence of flutter in a simplified blade cascade is analysed. The simplified blade cascade is formed by three flat plates, which perform a kinematic harmonic motion, each with a different inter-blade phase angle. The inter-blade phase angles are chosen in order for travelling wave mode of vibration to be present. The aim of the simulations is to determine the aerodynamic damping coefficients caused by the aerodynamic forces acting on the flat plates, which show whether flutter occurs. The non-linear system of Favre-averaged Navier- Stokes equations in ALE formulation completed by the Spalart-Allmaras turbulence model was chosen as the mathematical model. The simulations were performed using the developed inhouse CFD software FlowPro based on the discontinuous Galerkin method, which offers high order of accuracy.
