Kurzfassung englisch:
Functional gaps of cars combined with the underlying volume of air represent Helmholtz resonators that are excited at the
Helmholtz frequency by the turbulent flow. Based on a model that describes the spatial coherence of pressure fluctuations
beneath a turbulent boundary layer, we present how to compute an extensive synthetic excitation signal without performing
computational fluid dynamics (CFD) computations. Moreover, this contribution shows the capabilities of complex fluid
models to better predict the resonance behavior of Helmholtz resonators.
