Shell Eco-Marathon: aerodynamics analysis

Abstract

The objective of this Project is to achieve a study of engineering for a small urban car, which meets the normative of the Shell Eco-Marathon. The idea is to achieve a study of aerodynamics, of the back, of three different shapes, and to reach the conclusion of this is the more adequate since the point of view aerodynamics, and hence, in the consumption less quantity of fuel. Of the three models that are used for studied, two are models that it is in the laboratory. This models it¿s employed for study the back of the vehicles, changing the part back, which is that vary the angle back. The third model, has been construed, the motive of its construction and its dimensions will be announced later in the other paragraph. The final step, after of to create the model and of choose the two models; it is made the testing in the wind tunnel. Subsequently of the data obtained have reached conclusions about which are the shape rears more appropriate for reduced the aerodynamics force. This model has been to test in the smoke tunnel. In this type of tunnel can be to see the airflow around the vehicle.
