I refer to ANY computational method focussing on the computation of the sound associated with a fluid flow as computational aeroacoustics - (CAA). The CAA methods are strongly linked to CFD CAA methods use specific techniques to resolve wave behavior well which makes this different than general computational fluid dynamics (CFD).
impedance is educed using (1) an analytical approach based on the assumption of a single, dominant, propagating mode,6 or (2) a 2-D finite element method (FEM) that characterizes wave propagation through the lined duct.9 Based in part on the results of a comparison study of impedance eduction techniques used by various U.S. aeroacoustics
