Of the globally available fuel resources 77% is taken by ground automobiles, which accounts for nearly 40% of global air pollution and emission of greenhouse gases. Ultimately drag being the main reason for fuel consumption. Based on study 15% reduction in drag at a highway speed of 55mph can result in 5-7% of fuel savings. The prime methodology of the project is to attach a device to the existing vehicle and analyse the wake region at the rear end, using the numerical model k-Epsilon in the Ansys Fluent 17 platform. Two-dimensional model of the majorly used cars are generated without any modifications using Catia V5 modelling software. Then the same model is designed with an add on device. Flow around both unmodified and modified vehicles are analysed and compared for drag coefficient. A rectangular enclosure is constructed in the Design Modeller and the model is subtracted with Boolean operation. The domain is finely meshed. Boundary conditions are given in accordance to the road transport environment, calculations are done with velocity inlet and pressure outlet. The graphs are plotted for Cd and Cl. The contours are then recorded at each trial for pressure and velocity. The results are then compared. There occurs a significant reduction of about 1.29 to 0.98 in drag coefficient which is about 24% of decrease of drag from the existing vehicle to the modified vehicle.
