This paper aims to design the double-element airfoil for application on the front wing of a student formula car by using CFD (computational fluid dynamics) with the Reynolds Averaged Navia-Stokes (RANS) model. The design method is done by simulating the flow on a single-element airfoil to determine the separation point of fluid on the airfoil surface. The point is then used to divide the airfoil into the double-element airfoil, followed by analysis to find the right angle to achieve maximum downforce. The simulation results indicated that the angle of attack of 3° and the second element wing angle of 30° give the maximum Cl of 4.837, which can create downforce on the front wing of 884.3 N. It can be concluded that the designed double-element airfoil provides better downforce values than a single-element airfoil.
