Abstract
In the development of the times and technology, demands for forms and characteristics have a good aerodynamic value. As a result, various types of new models are emerging rapidly in the automotive market. In addition, many drivers modify their cars. One of them is by adding a body kit or just adding a spoiler to make it more esthetic. As time goes by, many car manufacturers pay attention to several aspects in designing their cars. One of them is aerodynamic. The aerodynamics performance of a car is affected by the drag coefficient (Cd) or drag when the car is in motion. Furthermore, to get this Cd value, a study will be carried out that focuses on the effect of adding spoilers with NACA 2412 on vehicles. The research can be carried out using the CFD simulation. In the study, a simulation was carried out using a Hatchback car and two spoiler models with a NACA 2412 airfoil profile. The result obtained is that a car without a spoiler produces a Cd of 0.562, and for a car model with a spoiler 1, it produces a Cd of 0.383, while for a car with a spoiler of 2 it produces a Cd of 0.409.
