Abstract

Symmetric airfoils like NACA 0015 have limitations in generating lift force compared to asymmetric airfoils. Therefore, additional devices are needed to overcome this limitation, A plain flap is one of a device that can be used to enhance the lift force on the airfoil. This study aims to analyze the impact of a plain flap on the aerodynamic performance of the NACA 0015 airfoil, emphasize the Lift Coefficient (Cl) and Drag Coefficient (Cd). Data for this research is collected through the utilization of Computational Fluid Dynamic method. Simulations were run at a Reynolds number of 4 million using the k-Epsilon turbulent model. Three variations of geometry models were simulated: NACA 0015 base model and NACA 0015 airfoil with a plain flap at a deflection angle of 15° and 30°. All three geometry models were subjected to variations in the Angle of Attack that ranges from 0° to 25°. The results demonstrate that implementing a plain flap at deflection angles of 15° and 30° significantly increases the maximum airfoil's coefficient of lift. The initial maximum lift coefficient of NACA 0015 is 1.15 improved to 1.5 and 1.71, respectively. However, incorporating a plain flap result in a notable rise in drag. On average, the Drag Coefficient experiences a 65% increase at a plain flap angle of deflection of 15° and a 178% increase at a plain flap angle of deflection of 30°.
