Abstract
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.
