Comparison of computational approaches for the efficient analysis of airfoil dynamics
Popis výsledku v původním jazyce
The paper deals with the comparison of two different computational approaches for modeling the incompressible fluid flow of airfoil with the flow field in order to find an effective tool suitable for the stability analysis of the investigated system. The content of the paper includes two analysis aimed at comparing the force effects acting on the fixed airfoil geometry and also the analysis of the airfoil vibration response to the excitation by the flow field. The main tools of the analysis are the panel method represented by XFoil software combined with the analytical approach of 2D rigid body modeling and the complex CFD analysis based on the modeling of the incompressible fluid flow using a nonlinear system of the Reynolds-averaged Navier-Stokes equations implemented in ANSYS Fluent software. Used turbulent models were primarily the one-equation Spallart-Almaras and the two-equation SST k-omega. The obtained results are validated with previously published experimental data. Presented methodology represents a first step towards the development of an efficient solver for the stability of airfoils.
