The aim of this work is on one hand to gain a better understanding of the aerodynamics of an airfoil working in a turbulent flow. The simulations are then compared and validated with already available load measurements. Special attention is paid to the resulting loads. In this work a DES numerical study of the flow around a Wortmann FX 79-W-151A airfoil is performed for different turbulence intensities. This leads to great uncertainties in the design process, which in turn make wind turbines less reliable and cost-effective. However, the design of the rotor blades is usually based on experimental results of airfoils operating under laminar conditions. The aerodynamic behavior of wind turbines is strongly influenced by the turbulence level.
