Kurzfassung
A new validation of the source localization method SODIX for coherent sound sources is presented. The DLR fan noise prediction tool PropNoise is used to model the tonal noise of a low-speed fan stage that is generated by the interaction of the rotor wakes with the stator vanes. The simulated data is used to evaluate the capabilities of the source localization method SODIX to determine the coherent sound radiation from the intake and the nozzle exit. The analysis technique includes a parameterization of the source directivities using cubic B-splines. A parametric study on the number of base elements is carried out for the simulated tones with different radiation patterns. The results show that SODIX is able to accurately reproduce the coherent sound radiation of the simulated tones from the intake and the nozzle exit. The results also indicate that a number of base elements from 20 to 100 is a reasonable choice for a large frequency range.
