1. Aim and purpose of this project
Nowadays, car has been one of the main vehicles to travel. However, the space offered in the boot is not enough for all the luggage. Consequently of this problem, appeared the idea of putting an extra luggage in the roof of the car. These boxes called roof boxes had an important effect in the whole vehicle modifying the specifications of the car. One of these effects is an increase of fuel consumption. Fuel consumption is one of the most important factors to choose one vehicle than other, consequently installing a roof box has to modify the specifications of the car as little as possible.
The purpose of this project is analysing which effects has in the vehicle specifications when a user install a roof box on the top of the car. As we know, an increase of weight in a car is translated in an increase of fuel consumption. Otherwise the user does not know that depending on the forms of the roof box, the aerodynamic of the car is modified producing an increase the fuel consumption. Therefore, in this project we are going to analyse one of the most popular and commercial roof box (Thule Large Box 634s) and we are going to verify which effect has in his flow, the increase of cD and finally how the motor dynamics of the vehicle is altered. Another objective of this project is to redesign a new roof box. The idea of this new roof box is to improve the aerodynamic of the car and verify which effect has in the car. However, this new redesign of the roof box has to conserve the effectiveness of this. It means that the volume and the dimensions of the roof box should be very similar with the original model.
To analyse this effects, the programs used in this project are SolidWorks (CAD design) and Ansys Fluent (Engineering simulation software). Consequently of using this program, this project allows us to apply, learn and link technical knowledge of aerodynamics and computer knowledge.
To sum up, we expect with this project to analyse how effective is a commercial roof box and improve the aerodynamics and reduce the fuel consumption when the car is circulating.
