Özet
The aerodynamic force of vehicles has been affected by the geometric shape of front surface. The aerodynamic force of a scaled bus model and CD were experimentally determined in wind tunnel. The experimental tests were conducted at 6 different free flow velocities. They were performed in the range of 3.8×103- 7.9×103 Reynolds number. The drawing data of model bus were obtained by 3D scanned and drawn in Solid Works program. The circular cross section flow control rod was designed in 10 mm, 20 mm and 30 mm diameter and positioned at 3 different locations (L/H) on the model bus. By this passive flow control method, aerodynamic drag reductions were obtained up to 10.06%, 7.35% and 7.85% respectively.
