Öz

Bu çalışmada yan aynaların yerine kamera sistemlerinin kullanılmasıyla yakıt tasarrufu potansiyelinin araştırılması için sonlu elemanlar yöntemi kullanılmıştır. Drag katsayısı, aerodinamik direncin bir ölçüsü olduğundan, yakıt tasarrufu üzerinde önemli bir etkisi vardır. Yan aynaların yerine kamera sistemlerinin kullanılması, araçların aerodinamik profilini iyileştirebilir ve drag katsayısını azaltabilir. Bu çalışmada bir otomobil modeli üzerinde sonlu elemanlar yöntemi kullanılarak drag katsayısı hesaplanmıştır. İlk olarak, aracın yan aynaları yerine kamera sistemlerinin entegrasyonu simüle edilmiştir. Elde edilen sonuçlar, yan aynaların yerine kamera sistemlerinin kullanılmasının drag katsayısını düşürebileceğini ve bu yüksek hızlarda kamera sistemlerinin daha iyi aerodinamik performans sağladığı tespit edilmiştir. Bu bulgular, yaygınlaştırılması ve yakıt tasarrufunun artırılması için önemli bir bilgi sunmaktadır. Araştırmanın sonuçları gelecekte yapılacak çalışmalar ve otomobil tasarımında aerodinamik iyileştirmeler için rehberlik edebilir. Bu çalışma, yan aynaların yerine kamera sistemlerinin kullanımının yakıt tasarrufu açısından önemli bir potansiyele sahip olduğu ve bu yöntemin otomotiv endüstrisinde daha fazla uygulanması gerektiğini vurgulamaktadır.

THE EFFECT OF USING CAMERAS INSTEAD OF SIDE MIRRORS IN VEHICLES ON FUEL CONSUMPTION

Öz

In this study, the finite element method was employed to investigate the fuel-saving potential of replacing side mirrors with camera systems. Since the drag coefficient is a measure of aerodynamic resistance, it has a significant impact on fuel efficiency. Utilizing camera systems instead of conventional side mirrors can enhance the aerodynamic profile of vehicles and reduce the drag coefficient.In this research, the drag coefficient was calculated using the finite element method applied to a car model. Initially, the integration of camera systems in place of side mirrors was simulated. The results indicated that replacing side mirrors with camera systems can lower the drag coefficient and provide improved aerodynamic performance, particularly at high speeds.These findings offer valuable insights that support the wider adoption of camera systems to enhance fuel efficiency. The outcomes of this study may guide future research and inform aerodynamic improvements in vehicle design. This work highlights the significant potential of camera systems as alternatives to side mirrors in achieving fuel savings and emphasizes the need for broader implementation of this approach within the automotive industry.
