Abstract

Large Eddy Simulations (LES) of turbulent flows around a segment of the FX-79-W151 airfoil have been performed for different Reynolds numbers between Re = 5 ⋅10^3 and Re = 10^5 and the angle of attack 12∘ using a Spectral Element Method (SEM). The results of the LES for Re = 5 ⋅10^3 and Re = 5 ⋅10^4 are compared. The turbulence statistics obtained in the LES reveal laminar and turbulent flow separation regions for the lower and higher Reynolds numbers, respectively.
