Abstract

Aerodynamic design of a vehicle is one of the crucial elements for fuel consumption and its performance. Nowadays, the improvement of the fuel consumption of a car has become a significant factor in car production. This is due to the rising of fuel pricing and declination on the fossil fuel production. The main goal of aerodynamics is to reduce drag and wind noise. A small change to the body design can affect the drag coefficient of the car especially by changing the shape of front face since it contributes the effect up to 65% for the front face. Thus, this project is focusing on shape optimization on the front portion of the Shell Eco-Marathon urban car to get the most aerodynamic design without compromising its aesthetic look. The major objective of this study is to analyse and examine the effect of purpose modification on frontal area of a car to the aerodynamics characteristic. A three-dimensional design of Mercedes Benz CLA 2013 car was carried out by using CATIA V5 software as a benchmarking model. Three type of modification is made on this model and used to determine its aerodynamics characteristic. ACU Solve software from Altair is used for the computational fluid dynamics (CFD) analysis. The result shows an excellent optimization for the benchmarking model as the drag coefficient is reduce by 14.18% for the final model. From the CFD result, it is clear to see that by only increasing the windshield angle, and the height of the hood has a significant influenced on reducing the drag coefficient as well as have a better pressure distribution and better streamline airflow.
