Abstract

Coaxial jets originating from a nozzle interacting with a two-element wing configuration consisting of a main wing and a flap are computed using large-eddy simulations (LES) to investigate in the long term the effect of the interaction on the sound field of this jet-wing-flap configuration. The secondary jet Mach number is \(M_s=0.37\) and the Reynolds number based on the secondary velocity and diameter is \(Re_{s}=1.32 \times 10^6\). The nozzle inlet boundary layers are modeled by Blasius velocity profiles with a boundary layer thicknesses of 20% of the nozzle channel half-width. The acoustic far-field is predicted by solving the linearized Euler equations (LEE) in a region attached to the LES domain. The jet streams interacts with the two-element wing configuration and lead to a significantly changed mean flow field in the wing-flap gap area and pressure at the wing surface. Additionally, a strong influence of the flap on the jet development is observed, especially in the case of a non-zero free stream velocity.
