Abstract :This study focus on reducing the aerodynamic drag force on a ground vehicle model with a spolier model. The spoiler model was designed to delay the flow separation and passive flow control. A 1/15 scaled vehicle model was used in wind tunnel tests. That vehicle model uses in passenger transportation sector. The spoiler model was designed in the SolidWorks® and produced bu using a 3-D printer. The spoiler was mounted on front roof area of vehicle at 10% and 5% (L/H) rates.. The wind tunnel tests were carried out at four different free-flow velocity speeds. The drag coefficient was reduced by 3.93% in model 1 and 2.86% in model 2. Flow separation was delayed and decreased by this flow control part application on vehicle. These drag reductions can decrease the fuel consumption of vehicle models by about 2% at high speeds.
