N2 - Large-eddy simulations (LES) are carried out for flows over a NACA 0015 airfoil at AoA = 8o and a chord based Reynolds number of 1.71 × 106. To accurately simulate the complex flow on the suction side of the airfoil, a reasonably large number of grid points is required. The computational mesh is constructed in a wind tunnel similar to the LM wind tunnel where the experiment for an NACA 0015 airfoil was carried out. The goal of this study is to validate the mixed scale SGS turbulence model against detailed measurements. Simulations are performed with the in-house EllipSys3D code on high performance computers. The stability and accuracy of the LES simulations are studied on various mesh configurations. The spanwise grid spacing is found important to produce correct flow disturbances <br/>along the airfoil span, which can affect the turbulent energy distribution.
