Abstract

Bu çalışmada, aerodinamik analiz kullanılarak bir arabaya etki eden sürükleme kuvveti incelenmiştir. Analizde genel bir araba modeli kullanılmıştır. Bir araç hareket ederken havanın oluşturduğu dirençten kaynaklı oluşan sürükleme kuvvetine maruz kalmaktadır. Sürükleme kuvveti bağıl harekete karşı bir dirence neden olur. Dolayısıyla aracın yakıt tüketimini doğrudan etkiler. Analizler, araçların izin verilen maksimum hız limiti olan 130km/s’de yapılmıştır. Yan camların açık veya kapalı olma durumlarında sürükleme kuvvetinin nasıl etkilendiği araştırılmıştır. Çalışmalar, araçta oluşan sürükleme kuvvetinin ön camlar açıldığında %2’ye kadar, arka camlar açıldığında %4’e kadar olumsuz etkilendiğini göstermektedir.

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.
