Abstract

[A wide range of far field sound prediction techniques is outlined. Also, their hybridization is considered. Computational process challenges relating to connecting the flow field simulation elements outlined in previous chapters to the acoustic propagation methods is discussed. The form of acoustic source correlation coefficients is given. A range of eddy resolving simulations used for acoustics is reviewed. The frequency of use of different eddy resolving, numerical schemes and far field sound prediction approaches in acoustics is assessed along with validation data levels. Areas where validation is lacking are outlined. The use of LES to define low order acoustics models is considered. The need for more holistic simulations is identified.]
