An Engineer is always focused towards challenges of bringingideas and concepts tolife.Therefore,Software and Computer Techniques must beconstantly developed and implemented forVirtual and Economic Analysis. At the same time, we must take care thatthere is no compromise with the Accuracy ofthe Techniques used. In the Age of Speed, Automobiles have become an integral part of human routine. By designing Aerodynamically SoundAutomobiles, overall efficiency of an Automobile can be increased, by reductionin the Drag Force (Losses) and too by the reduction in the Fuel Consumption,eventually developing an Environment-Friendly Vehicle. The Engineer is constantly conformed to the challenges of bringing ideas and design into reality. The Computational Fluid Dynamics is a steptowards bringing numerous Hypothetical Concepts to reality, as the Analysisdone gives better results compared to the Physical Analysis (Wind TunnelTesting), without any costly setup and space requirement. In this Project,Modelling of Automobile (Car) was done using the Software-Solid works. The Liftand the Drag of the car were determined by the Analysis of Fluid (Air) Flowaround it using Software-Ansys Fluent. After that, with modifications like AirVents, Rear Spoiler, the Analysis was repeated. Based on the values of LiftForce and Coefficient of Drag (Cd), optimal solution was consideredas the success of the Project.
