Abstract: CFD analysis of the flow field around four different automotive rear spoiler configurations is carried out to determine the best amongst them, for the purpose of reducing the drag as well as improving the negative lift on the vehicle. A spoiler is the additional fixture, generally placed either on the front or rear side of vehicle to maneuver the flow field, to destroy wake zones and create downward force thereby reducing pressure drag and enhancing the negative lift force. This results in reduced fuel consumption and better traction of the vehicle. The four different spoilers arrangements considered in the present study are single spoiler, linear multispoiler with horizontal offset of 0.2 units. Multispoiler with aft spoiler at bottom, multispoiler arrangement with aft spoiler on the top with vertical offset of 0.2 units. CFD results revealed that multispoiler configuration with aft spoiler produces least drag while multispoiler with aft spoiler on the bottom gives the best traction.
