Abstract

We assess the applicability of the IDDES method for modeling acoustics generated by a multielement aircraft wing with deflected high-lift devices. The testing is carried out using the flow around an unswept 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, and 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.
