Nowadays, the resolution of Aeroacoustic problems using numerical methods (CAA) is currently a very active area of research, with great industrial interest. However, the simulation of the sound propagation is a very difficult numerical problem, and moreover, most of industrial applications present complex geometries. Thus, numerical methods successfully used in unstructured grids in aeronautics fail when applied to CAA. This is due to the excessive amount of dissipation and not enough spectral resolution of these schemes. In this paper we present the application of a high-order finite volume method based in Moving Least Squares (FV-MLS) to the simulation of acoustic wave propagation in complex domains. This work continues the work of the authors in the development of numerical methods to be used in the resolution of acoustic problems of engineering interest.
