The aim of this work is to assess the prediction capabilities of the turbulence models and the transition model kkl-omega available in OpenFOAM and to achieve a database of airfoil aerodynamical characteristics. The airfoils chosen for the simulations are FX 79-W-15A and NACA 63-430, which are widely used in wind turbines. The numerically obtained lift and drag coefficients are compared with available experimental results. A quantitative and qualitative study is conducted to determine the influence of meshing strategies, computational time step together with interpolation and temporal schemes. Two Reynolds Averaged Navier-Stokes models (RANS models) are used, which are the k-omega SST model by Menter and the kkl-omega model (which involves transition modeling) by Walters and Davor
