AbstractAeroacoustic simulations associated with noise radiation from the leading-edge slat is conducted. The shear layer emanating from the slat cusp and its subsequent reattachment upstream of the slat trailing edge lead to a primarily broadband noise spectrum. Often, however, the slat noise spectrum also exhibits narrowband peaks superimposed on the broadband portion, especially in the case of unswept wind tunnel configurations at lower than full-scale Reynolds numbers. In this study, influence of wing sweep angle on the slat noise characteristics, especially on the narrowband peaks, is investigated by aeroacoustic simulation using Delayed Detached Eddy Simulation around the 30P30N three-element high-lift airfoil configuration.
