CFD SIMULATION OF THE TURBULENCE MODEL K-ω SST APPLIED TO RECTANGLE 1:4.9

The analysis of flutter coefficients is important for the development
of projects in the field of structural engineering. These coefficients can be
obtained via wind tunnel or via numerical simulations through Computational
Fluid Dynamics (CFD). In this work, an analysis of the flutter coefficients of
rectangular section 1:4.9 submitted to a turbulent flow with Re = 105, with
turbulence model k-ω SST was presented. A numerical model to solve the incompressible
Navier-Stokes equations was proposed using the open source software
OpenFOAM®. Finally, the results obtained were validated and considered
satisfactory, concluding that the CFD proved to be useful in solving problems
involving the flutter phenomenon.
