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 e ciency 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.",
