A selective overview of high-order finite-difference schemes for aeroacoustic applications

By Ivan Spisso and Aldo Rona


This paper was published as Proceedings of the 14th International Congress on Sound and Vibration, Cairns, Australia, 9-12 July 2007, pp. 1-8.The Fourteenth International Congress on Sound and Vibration (ICSV14) was sponsored by the International Institute of Acoustics and Vibration (IIAV) and the Australian Acoustical Society (AAS).A variety of aeroacoustic problems involve small-amplitude linear wave propagation. Highorder\ud schemes have the accuracy and the low dispersion and dissipation wave propagation\ud properties that are required to model linear acoustic waves with minimal spatial resolution.\ud This review presents a selection of high-order finite difference time-explicit schemes for aeroacoustic\ud applications. A scheme selection method based on the computational cost for a given\ud accuracy level is proposed
