Karabasov, SA and Hynes, TP (2005) An efficient frequency-domain algorithm for wave scattering problems with application to jet noise. Collection of Technical Papers - 11th AIAA/CEAS Aeroacoustics Conference, 1. pp. 347-358.Full text not available from this repository.
This paper presents a pseudo-time-step method to calculate a (vector) Green function for the adjoint linearised Euler equations as a scattering problem in the frequency domain, for use as a jet-noise propagation prediction tool. A method of selecting the acoustics-related solution in a truncated spatial domain while suppressing any possible shear-layer-type instability is presented. Numerical tests for 3-D axisymmetrical parallel mean flows against semi-analytical reference solutions indicate that the new iterative algorithm is capable of producing accurate solutions with modest computational requirements.
