LARGE EDDY SIMULATION OF A TRANSIENT SPOILER DEPLOYMENT IN A NACA0012 PROFILE IN SUBSONIC AND TRANSONIC SPEEDS
R.V. Linn¹, A.M. Awruch¹; ¹Federal University of Rio Grande do Sul, Brazil
THE TRANSIENT SPOILER DEPLOYMENT IN A NACA0012 PROFILE IS HERE STUDIED USING LES FOR THE TURBULENCE MODELLING, ADAPTATIVE MESH TECHNIQUES AND MESH MOVEMENT WITH FEM. SUBSONIC AND TRANSONIC SPEED RANGES ARE INVESTIGATED FOR A REYNOLDS NUMBER OF 350000. THE TRANSIENT LIFT AND DRAG COEFFICIENTS ARE PRESENTED, SHOWING THE AERODYNAMIC CHANGES OF THE PROFILE ALONG THE MOVEMENT OF THE SPOILER.
