DDES and OES Simulations of a Morphing Airbus A320 Wing and Flap in Different Scales at High Reynolds

The present study concerns the use of unsteady numerical simulations by means of Navier Stokes Multi Block (NSMB) solver including both high order schemes and turbulence resolving methods. Firstly, this work attempts to highlight the role of the morphing applied to the supercritical Airbus A320 wing and flap in the trailing-edge for a Reduced Scale (RS) prototype at the clean position, this morphing includes a slight deformation of the trailing edge with a selected frequency and amplitude, which has an impact on the flow near the trailing edge and specially in the wake structures. This solution can transform the 3-dimensional chaotic flow into a 2-dimensional one by enhancing coherence of 2D structures rows of von Karman vortices. In Addition, the highlift A320 wing-flap at the take-off position in Large-Scale (LS) configuration have been studied using advanced hybrid models DDES, the Organised Eddy Simulation OES and SST for the RANS regions as well as LES Smagorinsky model.
