Summary:

A vehicle's performance and fuel economy plays an important role in obtaining a larger market share in the segment. This can be best achieved by optimizing the aerodynamics of the vehicle. Aerodynamics can be improved by altering the bodylines on a vehicle. Its drag coefficient can be maintained at a minimum value by properly designing various component profiles. The stability of a vehicle and Passenger comfort are affected by wind noise that is related to the aerodynamics of a vehicle. To study the effects of the above-mentioned parameters, the vehicle is tested inside a wind tunnel. In this paper, the authors study the body profile for different vehicles and analyze them using Computational Fluid Dynamics software - FLUENT. To study the influence of different body profiles on drag coefficient, 3 different vehicle segments are considered. This paper discusses the methodology followed, to test the vehicle models in a simulated environment and the physical parameters on the profiles are compared and analyzed. The author also discusses the type of algorithms used in solving the Navier-Stokes equation to obtain the results. Drag coefficient being one of the important parameters during design, is computed from the results
