Applications of a high-order algorithm for LES and CAA in complex geometries

High sound pressure levels are produced by non-linear interactions between acoustics and aerodynamics in confined flows. To tackle these couplings, a numerical tool called Code Safari has been developed. The solver is based on optimized high-order finite-difference schemes combined with optimized filters on a multi-domain approach. In addition, a shock-capturing filter has been implemented to deal with compressible flows. This solver has been validated on classical test problems and key results obtained for three realistic applications, namely noise generated by ducted cavity, sudden enlargement and by rod-airfoil interaction, are reported
