| Summary: | During this last decade, automotive industry has been focusing on the efficiency of the cars. The fuel consumption regulations, combined with the range of electric cars, have set a critical design factor: fuel consumption. Among all the design areas involved, aerodynamics take a great role in that objective, as more aerodynamic elements are added to everyday cars in order to reduce drag, making cars more efficient. One component that car manufacturers are starting to include is the air curtain, located in the car’s bumper, with different configurations depending on the car manufacturer. In this work, a study of these air curtains will be carried out, from the design of two configurations based on real geometries, to its aerodynamic behaviour to finally understand if their implementation indeed improves the vehicle’s aerodynamic performance against drag, also known as aerodynamic resistance. |
