Titel:
Parametric LES/SI based aeroacoustic characterization of tandem orifices in low Mach number flows 
Abstract:
Acoustic scattering and noise generation in tandem orifice configurations are examined and modelled. The modelling is carried out by a combination of Large Eddy Simulation (LES) and System Identification (SI). Hereby, an acoustically excited LES is performed. Afterwards, the acoustic data series extracted from the LES domain are post processed by means of parametric SI methods to concurrently identify both acoustic scattering and noise sources. Adopting a system theory perspective, the scatter...    »
