Abstract

Airfoil is a geometric shape that when placed in a fluid flow will produce a lift greater than the drag force (drag). With the slightly curved side of the airfoil, there is a point of separation in the airflow passing through the airfoil. In this research, aerodynamic testing is carried out, using numerical simulation with Ansys software. This study used NACA 23018 specimens which were given variations of the vortex generator and swept back wing. The type of vortex generator used is a triangular vortex generator with a length of 25 mm, and a height of 10 mm with a straight installation. The distance of the vortex generator to the leading edge is x/c = 10% and 15%, the swept angle is 15°, and the angle of attack varies. The freestream speed used is 20 m/s. Simulation results on the airfoil with the addition of a vortex generator can affect both performance and aerodynamic characteristics. The vortex generator on the airfoil can delay the airfoil separation, and can also delay the stall where the plain airfoil stalls at α = 15° with the addition of the vortex generator that has not stalled at this angle of attack. A vortex generator can affect the value of C_L/C_D. Overall, the most optimal variation of the vortex generator is the vortex generator with x/c = 15% where the C_L/C_D value is greatest at an angle of attack α = 12° which is 13.13.
