Abstract
Research on aerodynamics of cars is fairly complex and wide area for exploration. Over the past few decades engineers has invested substantial amount of effort in research and development in the aerodynamics sector and has resulted in significant improvements to the vehicle designs. Thanks to the cost inflation and greenhouse gas emissions concerns which has put even more serious actions in place in terms of improving fuel efficiency.
Newly developed cars are much more safer and fuel efficient compared to the cars more than a decade ago. This has to do with the reduction in aerodynamic forces namely, the drag force, which affects the fuel efficiency and, the lift force, which affects the stability and cornering of the car. These effects are highly dependent on the shape of the car, as well as the speed and environmental factors such as highways, cross winds etc.
This research project is reviewing some literatures and will carry out some investigations and design simulations on a rear spoiler design for cars. This will try to understand if an improved down force cab be achieved without an increase in drag force. The main objective is to design a new and profiled spoiler design.
There will be 3 cases considered for the analysis.
Case 1: A sedan car model. (This car is used in all three cases as a base car)
Case 2: Car with a generic rear end spoiler
Case 3: Car with profiled spoiler with webbed edges (new design)
More details on research gap, spoiler design features and project objectives are provided in section 3 – Research Analysis. The first two cases will be compared with the results obtained from the new spoiler design (third case) in order to determine the effectiveness of the proposed design.
It is to be noted that the first two cases are generic and existing solution and there is no knowledge gap claimed in this report. All 3D models for car and spoilers are developed in Autodesk Inventor and will be exported to Ansys Fluent for CFD analysis.
