We assess the applicability of the IDDES method for modeling acoustics generated by multi-element aircraft wing with deflected high-lift devices. The testing is carried out using the flow around unsweep wing segment based on the 30P30N airfoil. The near-field acoustics and aerodynamics obtained by the computations are compared with the experimental data. Far-field acoustics is modeled by the FWH method, the resulting spectra and radiation pattern are presented in the paper. We also test the application of sponge layers on the segment borders as an alternative to the periodic boundary conditions; the corresponding effects on the numerical solution are demonstrated.
Keywords: EBR scheme, validation. sponge layer.
