English abstract:
In low Mach number aeroacoustics, the well known disparity of length scales
makes it possible to apply well suited hybrid simulation models using different
meshes for flow and acoustics, which leads to a powerful computational procedure.
In general, hybrid aeroacoustic methods seek for robust and conservative mesh
to mesh transformation of the aeroacoustic sources while high computational
efficiency is ensured. We investigate the accuracy of a standard conservative
interpolation scheme compared to the more accurate cut-volume-cell approach
and their application to the computation of rotating systems, namely an axial fan.
The capability and the robustness of the cut-volume-cell interpolation in a hybrid
workflow on different meshes are investigated by a grid convergence study.
