Abstract: The primary goal of this research is to introduce a novel method for reducing drag of the NACA 0012 airfoil, aiming to enhance its aerodynamic performance. This involves strategically placing a specialized device in areas where flow separation occurs. The primary purpose is to decrease drag of the airfoil, ultimately leading to improved efficiency. To thoroughly explore this approach, extensive two-dimensional numerical simulations have been carried out, employing the computational fluid dynamics (CFD) capabilities of Ansys Fluent 17.0. The analysis is based on conditions of incompressible and laminar airflow, with particular focus on a Reynolds number of Re = 1000 and a 5° angle of attack. The resultant outcomes highlight instances in which the device effectively reduces drag while simultaneously enhancing the lift-to-drag ratio. Looking ahead, future research works include a more comprehensive investigation of this innovative drag reduction device across a wider range of angles of attack, thereby expanding its potential applications.
