3D numerical simulations are performed around the Reduced Scale A320 wing prototype of the H2020 N°723402 EU project SMS: “Smart Morphing and Sensing for aeronautical configurations”, https://cordis.europa.eu/project/id/723402/fr, www.smartwing.org/SMS/EU. The wing has 70cm chord and 56cm span and is investigated in the subsonic regime at Reynolds number 1 Million and for 10° incidence using the Navier Stokes Multi-Block (NSMB) code. Bioinspired electroactive morphing is numerically investigated through vibration and slight deformation in the near trailing edge region, using the ALE method for mesh deformation and the Organised Eddy Simulation (OES) turbulence modelling approach, [1], sensitized to the coherent structures physically correct development, also including the DDES-OES case (Detached Eddy Simulation with embedded OES). Following a previous 2D numerical study [2], a linear time modulation of the trailing edge actuation frequency (wobulation) is carried out in 3D to efficiently detect optimal morphing frequencies providing aerodynamic performance increase.
