Identification of aero-acoustic scattering matrices from large eddy simulation_ Application to whistling orifices in duct

Abstract

The identification of the aero-acoustic scattering matrix of an orifice in a duct is achieved by computational fluid dynamics. The methodology first consists in performing a large eddy simulation of a turbulent compressible flow, with superimposed broadband acoustic excitations. After extracting time series of acoustic data with a specific filter, system… (More)
