EFFECT OF VARIOUS AERODYNAMIC DRAG REDUCTION METHODS ON VEHICLE- A REVIEW
Keywords:
Aerodynamic drag, drag coefficient, boundary layer, flow separationAbstract
Various technique to reduce the drag of bluff body through mechanism of back pressure recovery has been
investigated including spoiler, tail plate, vortex generator, rear suction and guide vane. Pressure distribution over external
surface has important significant for aerodynamic study of car. This review paper intends to provide information on recent
approaches and their efficiency in minimizing aerodynamic drag of vehicle. Study mainly focuses on methods employed to
delay flow separation at the rear end of vehicle body. Research carried out on different drag reduction technique and their
effect on aerodynamic drag is highlighted.
