COMPARATIVE ANALYSIS OF FLUTTER COEFFICIENTS TO THE RECTANGLE 1:4.9

The evolution of Computational Fluid Dynamics (CFD) and the achievement of results by experiments in wind tunnel, favor the analysis of aeroelastic coefficients. This study presents a comparative analysis of the flutter coefficients found via CFD and linear relationship by equations for a 1:4.9 rectangle subjected to turbulent flow with Re 10^5, applying the turbulence model to the simulation k-ω SST. OpenFOAM® was used to simulate the incompressible Navier-Stokes equations. Finally, the results obtained in the analyzes were validated and considered satisfactory, proving the effectiveness of this methodology.
