“…The rear spoiler redirects the airflow behind the vehicle, which in turn increases the negative lift of the vehicle. In case of vehicle, a negative lift force stabilizes it at high speed, increases capability to produce cornering force, gives better traction and improves braking performance [13,15,17,18].…”

“…Verma et al In order to increase the aerodynamic performance of a passenger vehicle, lip spoilers were applied to the rear of the vehicle and examined with CFD. As a result, they showed that the CD value decreased up to 6.9% at the spoiler angles between 6-10, and the CL value improved by an average of 12.9% [13]. Palanivendhan et al They aimed to reduce the drag coefficient with different vortex generator applications on the spoiler at different spoiler angles.…”

In this study, it is aimed to provide fuel economy and driving stability and comfort by reducing the drag coefficient by applying a spoiler to on an SUV model vehicle. The albatross type was preferred as the spoiler and it was mounted to the rear of the vehicle, as high as 10% of the total vehicle height. The model vehicle is 1/32 of its actual dimensions. The experiments were carried out at 4 different free flow velocities in the range of 2.08×103-5.35×103 Reynolds number. As a result of the experiment, it was determined that the use of spoilers reduced the drag coefficient value by 5.72%. Thanks to this study, it has been revealed that there is an improvement in fuel economy. Thus, it has been shown that aerodynamic performance can be improved by applying different spoiler applications in SUV model vehicles that are widely used today.

“…Tractive strength is generated by the moving vehicle. The tractive force tends to be limited by the amount of tangential force passed on by the wheels without spin [2]. The aerodynamic properties of a vehicle have a significant impact on its performance, handling, safety, and comfort, among other characteristics.…”

The goal of this research is to select the parameter of the car body at different velocity with different spoiler and to stimulate and analyse the drag coefficient and lift coefficient of the car body at different velocity with different spoiler. Moreover, aerodynamics in vehicles now play an important role. Aerodynamics affects vehicle performance by changing parameter such as lifting force and drag force, which play a major role in high speeds and fuel economy. The benefit of this research is to reduce drag and prevent undesired lift forces and other causes of aerodynamic instability when travelling at high speeds. For the analysis, the model is created in SOLIDWORKS and then imported into Ansys Workbench and Fluid Flow (Fluent) for further analysis. There are four models of car body in this simulation, which is Model 1, Model 2, Model 3 and Model 4. To collect data on the drag coefficient, lift coefficient, pressure contour and velocity streamline, this simulation was run at five different velocity which is 120 km/h, 140 km/h, 160 km/h, 180 km/h and 200 km/h. In conclusion, spoilers have a significant impact on drag reduction and the prevention of undesired lift forces.
