Abstract :To save energy and to protect the global environment, fuel consumption reduction is a primary concern of the modern truck manufacturers. Drag reduction is essential for reducing fuel consumption. Designing a vehicle with a minimized drag resistance leads to advantages of fuel economy and performance improvement. The shape is an important factor for drag reduction. To design a shape for an efficient truck that gives low resistance when moving forward, the most important functional requirement to consider is low fuel consumption. The resistance, termed as the drag force (or the drag coefficient in non dimensional terms), is a strong function of the shape of the truck. The main purpose of the project on which this paper is presented, was to reduce the drag co-efficient (CD) and drag force (FD) of a truck’s body by improving the aerodynamic shape using CFD software (Autodesk Flow Design). The difference of FD as well as CD before and after the change in aerodynamic shape of truck is carried out at different speeds. We got the desirable results for the reduction of drag force - about 12 to 15%.
