An aero-acoustic coupling method based on the splitting into noise sources generation and acoustic propagation in separate physical domains is presented in this paper. The key idea is to limit, as much as possible, the CFD domain to the noise generation region and to accurately propagate the acoustic waves with a CAA solver. The approach presented hereis a domain decomposition method based on the coupling of different equations, methods and meshes, which allows a simulation of both flow and acoustics in one single coupled calculation suitable for far field predictions with reflecting bodies through a coupling boundary.
