Drag reduction for a fast back passenger car (logan)
Journal Title: Science Heritage Journal | Galeri Warisan Sains (GWS) - Year 2017, Vol 1, Issue 2
Abstract
The car manufacturers all over the globe are intensively competing among each other in terms of the design and fuel consumption factor. Nowadays the reduction of drag is becoming a very important challenge for all the car manufacturers as they are producing powerful cars with better fuel consumption in the market regulated with law reinforcement on fuel emissions and consumers. Lower drag provides better performances such as higher top speed and better stability. It also often lowers aerodynamic noise and greenhouse gas emission above all decreases in fuel consumption. However, modern designs of cars tend to go higher and wider and thus they have higher frontal areas due to the functional, economic and aesthetic requirements. Increasing frontal area of the vehicle tend to increase the drag force acting on the vehicle which is proportional to the dimensionless drag coefficient and the projected area of the vehicle. Consequently, to hold or even decrease the drag on a car that has a larger frontal area, tremendous effort has to be made. In this research both experimental and numerical analysis have been done to an existing model of a car with some various aerodynamic add-on devices that can be attached to car and reduce aerodynamic drag of the vehicle without comprising on its main design features.
