| Sumario: | In this study the aerodynamic performance of a NACA 4412 airfoil profile under steady, incompressible flow conditions was assessed using computational fluid dynamics (CFD) analysis in ANSYS Fluent. The investigation focuses on identifying the stall angle by simulating the airfoil’s behavior across a range of angles of attack. After determining the baseline aerodynamic characteristics, active flow control is introduced through integration of jet actuators along the airfoil surface. The simulation assessed the efficiency of these actuators in delaying the flow separation and enhancing lift generation, minimizing stall effects. Results indicated that introduction of the actuators delayed stall onset while maintaining its aerodynamic stability and reaching the maximum possible angle of attack. The finding demonstrates the potential of active flow control to improve aerodynamic stability and efficiency. |
