Results from a numerical and experimental aeroacoustic assessment of 2D wind turbine blade sections are presented. CFD/CAA-based predictions using a synthetic turbulence method were conducted at a NACA 64-618 profile as well as at a new low-noise air

Edge noise is generated if turbulence interacts with solid edges. Reduction of trailing edge noise of airfoils can be achieved by replacing the solid material at the trailing edge by inlays of porous permeable material. The acoustic benefit of approx

Reliable predictions for wind turbines become more and more difficult with the increase in overall size and weight. On the one hand external factors such as the influence of wind shear become more important for bigger turbines, internal factors such

A Computational Aeroacoustic (CAA) study is conducted for the simulation of broad- band trailing-edge noise radiated from a NACA0012 airfoil and a cambered non-symmetrical DU96 airfoil for different ow conditions. The chosen simulation approach uses
