Aerodynamic Effect of Car Glass

Abstract

In the present work, the drag force acting on a car was examined using aerodynamic analysis. A general car model was used in the analysis. While a vehicle moves, it is exposed to the drag force caused by the resistance created by the air. The drag force causes resistance to relative motion. Therefore, it directly affects the fuel consumption of the vehicle. The analyses were made at 130km/h, which is the maximum allowed speed limit of the vehicles. It was investigated how the drag force is affected when the side windows are open or closed. Studies show that the drag force generated on the vehicle is negatively affected by up to 2% when the front windows are opened and by up to 4% when the rear windows are opened.
