ABSTRACT

The present paper describes the numerical analysis of the fluid flow around a finite span wing, NACA 0012 profile, provided with an aileron, placed at three static positions, corresponding to three different angles. The numerical simulation has been made with the commercial software ANSYS Fluent. The study is conducted in the case of the unsteady regime, the turbulence model used is SST k-ω, and the filtering of the governing equations is carried out under the DES (Detached Eddy Simulation) approach. The results show that the aileron position and velocity influences the flow and are leading to an aerodynamic instability at the trailing edge of the aileron, in some cases also influencing the wing end.
