A selective overview of high-order finite-difference schemes for aeroacoustic applications
conference contribution
posted on 2009-12-08, 16:17 authored by Ivan Spisso, Aldo RonaA variety of aeroacoustic problems involve small-amplitude linear wave propagation. Highorder
schemes have the accuracy and the low dispersion and dissipation wave propagation
properties that are required to model linear acoustic waves with minimal spatial resolution.
This review presents a selection of high-order finite difference time-explicit schemes for aeroacoustic
applications. A scheme selection method based on the computational cost for a given
accuracy level is proposed.
