Popis: 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 implementation is verified against a generic test case with homogeneous, isotropic porosity and a quiescent medium.
