A Low-Dispersion Finite Volume Scheme Applied to Computational Aeroacoustics
摘要
Abstract
The low-dispersion finite volume (LDFV) scheme is applied to thecell vertex-centered scheme.The interpolation coefficents of the two-order LDFV scheme are derived in detail.Based on this theory, an existing high accuracy upwind finite volume computer code is improved to achieve the obiect of low dispersion.As an example,the classical one dimension acoustic fluctuation transmits is calculated using the new code. Compared with the upwind scheme results and the theoretical values,it is showed that the LDFV scheme has the property of low dispersion and is suitable for aeroacoustic problem computation.关键词
