Assessment of various computational approaches for airfoil stability analysis with two degrees of freedom
Original language description
The paper compares different computational approaches in modeling the interaction of a 2D airfoil with 2DoF in the flow field. The displacements in the vertical and rotational directions, the values of the force effects acting on the airfoil, and the general stability of the structure as a dependence on the varied input parameters of the system are investigated. The analytical approaches represented by Theodorsen theory and the approaches derived from it to the explicit detection of the stability limit of the system (p method and U-g method) are compared with a complex CFD analysis based on the modeling of the flow field using Reynolds-averaged Navier–Stokes (RANS) equations implemented by ANSYS Fluent software. The results are validated with available experimental data.
