Abstract
Large Eddy Simulations of turbulent flows around a segment of the FX-79-W151 rotor blade have been performed for the Reynolds numbers Re = 5·10^3 and Re = 5·10^4 and the angle of attack 12° using a spectral element method with 8th order polynomials. The turbulence statistics obtained in the LES reveal regions of laminar and turbulent flow separation for the lower and higher Reynolds numbers, respectively, which lead to different loads on the blade.
