The sound generated by localized sources embedded in a jet is known to undergo the refraction as acoustic waves propagate through the mean jet flow. The principal objective of this paper is to develop an efficient and accurate method for the computation of the flow refraction in jets with realistic mean flow profiles, with and without the use of locally parallel flow approximation. The mean flow refraction problem is investigated by employing the reciprocity principle. Instead of direct source Green’s function, the authors apply the adjoint Green’s function with the source and interchanged observation points in order to quantify the effect of mean flow on sound radiation. The scattering/radiation problem is solved by computational methods of aeroacoustics. In appendix, the authors derive reciprocity relations for linearized Euler equations and give an example of multiple sources.
