Aerodynamic Efficiency Improvement on a NACA-8412 Airfoil via Active Flow Control Implementation

The present paper introduces a parametric optimization of several Active Flow Control (AFC) parameters applied to NACA-8412 airfoil at single post-stall Angle Attack (AoA) 15∘ and Reynolds number Re = 68.5×103. aim is enhance the efficiency maximize its lift. boundary layer separation point was modified using Synthetic Jet Actuators (SJA), carried on by systematically changing pulsating frequency, momentum coefficient jet inclination angle. Each case has been evaluated Computational Fluid Dynamic (CFD) simulations, being Averaged Navier–Stokes equations (RANS) turbulence model employed Spalart Allmaras (SA) one. results clarify which are optimum AFC efficiency. It also clarifies improvement in be expected under operating working conditions. An energy balance presented end paper, showing that for conditions studied saved higher than one needed actuation. how analysis performed can initially set as constant providing sufficient previous knowledge flow field already known. A maximum increase versus baseline around 275% obtained from simulations.
