Abstract
Large Eddy Simulations (LES) of turbulent flows around a segment of the FX-79-W151 rotor blade have been performed for different Reynolds numbers between $Re = 5cdot 10^3$ and $Re = 10^5$ and the angle of attack $12^circ$ using a spectral/hp element method (SEM). The instantaneous and statistically avergaged flow fields predicted in LES for $Re = 5cdot 10^3$ and $Re = 5cdot 10^4$ are analysed and compared. The turbulence statistics including the distributions of the pressure coefficients reveal regions of laminar and turbulent flow separation above the blade segment for the lower and higher Reynolds numbers, respectively. Finally some specific aspects regarding the application of the spectral/hp element method in LES are presented and discussed.
