Abstract
This paper investigates the efficiency of simulations for compressible turbulent flows with noise generation in complex geometries. It analyzes two different approaches and their suitability with respect to quality as well as turn around times required in industrial DoE processes. One approach makes use of a high order discontinuous Galerkin scheme. The efficiency of high order schemes on coarser meshes is compared to lower order schemes on finer meshes. The second approach is a 2nd order Finite Volume scheme, which employs a zonal coupling of LES and RANS to enhance efficiency in turbulence simulation. The schemes are applied to three industrial test cases which are described. Difficulties on HPC systems, especially load-balancing, MPI and IO, are pointed out and solutions are presented.
