Big percent of aerodynamic drag forces of road vehicles are pressure based. Therefore, it is important to examine the flow structure around the vehicles and take precautions against it. These studies are the subject of aerodynamics. Active and passive flow control are used to control the flow around the vehicle. In related studies, the use of CFD is a great advantage. In this study CFD method was used the verify of experimental drag reduction. The CFD tests were conducted at 6 different free flow velocities between the range of 3.8×103-7.9×103 Re. The model bus was drawn in SolidWorks after by 3D scanned. 10 mm, 20 mm and 30 mm diameter flow control rods were drawn and mounted at 3 different distance (L/H) to front surface of bus. CFD analyses were performed at the same test conditions for the least drag coefficient model. The experimental results were supported by CFD analyses in Fluent® program with 1.81% error margin. Detailed flow structures around the bus model and pressure distribution were determined by the CFD method.
