The Influence of Non-Local Property of Surface Acoustic Impedance on Acoustic Scattering
16th AIAA/CEAS Aeroacoustics Conference
The Influence of Non-local Property of Surface Acoustic Impedance on Acoustic Scattering is investigated in this paper. Firstly, an equivalent acoustic impedance model, proposed by Faverjon, has been put into acoustic scattering calculation. Combined with Spectral Collocation Boundary Element Method , , , , the theoretical deduction of acoustic scattering calculation has been conducted and the scattering of sphere covered with soundabsorbing materials has been calculated.
