Abstract
In a vehicle, aerodynamic drag force adversely affects flow and motion of vehicle, which in turn reduces its overall fuel efficiency. If the vehicle is redesigned to optimize its aerodynamic forces it could produce fuel efficiency. Effective way of controlling flow at rear end of vehicle is achieved by Vortex generators which are placed near rear windshield on roof line. With optimized angular placement of vortex generators, flow separation is reduced in automobile, effectively reducing pressure drag and hence improving fuel efficiency
