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

The derivation of a set of volume averaged perturbation equations is presented. The new governing equations allow predicting the effect of open type porous materials on the aeroacoustics of side or trailing edges of airfoils. The numerical implementa
