Abstracts: Aerodynamics is the study of moving gases (in this case air) over a body in motion, and how that airflow will affect the body's movement through the flow. In many, if not most, of the passenger vehicles we see on the road, aerodynamics plays a comparatively minor role in the overall design of the vehicle. Its major motive is to make a vehicle as aerodynamically safe as possible within specific design parameters. The bulkier or less streamlined a vehicle is, the greater force will be exerted upon it from air-drag as it pushes through (against) the air during acceleration. All things being equal, this cuts into fuel efficiency. It also translates to comparatively poor handling at high speeds when, in the case of an emergency, a sharp turn of the wheel is required to avoid hitting an on-coming object. There are many ways to decide the streamlines on Vehicle Body. One of these ways is Wind Tunnel, used for vehicle design (Cars, Trucks, etc.). Used for testing the different forces on vehicle body.
