Aeroacoustic Noise Source Identification Using Acoustical Holography 2005-01-2499

An integrated experimental/numerical technique based on nearfield acoustical holography (NAH) is developed to identify aeroacoustic noise sources associated with turbomachinery noise sources. An efficient enhanced surface potential formulation that is applicable for the resolution of complex noise source identification is developed for this purpose. Numerical examples are presented to validate the applicability of the presently developed formulation for the identification of aeroacoustic noise sources.
