Determination of flow resistance from acoustic in-duct measurements
2004 (English)In: Collection of Technical Papers - 10th AIAA/CEAS Aeroacoustics Conference, American Institute of Aeronautics and Astronautics, 2004, 494-504 p.Conference paper (Refereed)
This paper discusses the use of acoustic measurement techniques for determination of non-linearity and flow resistance of perforates and other facing sheets used in aircraft engine liners. Impedance measurements with pure tone excitation and random noise excitation are discussed as well as a non-linear system identification technique.
