Aeroacoustics topics at Merkle & Partner are primarily found in the vehicle sector, as the simulations are very complex and computationally intensive. In conventional flow calculations, small vortices are only considered in a smeared way via corresponding turbulence models. However, these vortices are relevant for noise generation, e.g. when the blower in premium segment vehicles starts up, and must be resolved both spatially and temporally. So-called LES methods are used here.
Aeroacoustics is mainly used in the automotive industry.
