This paper presents some experimental investigations to study the air flo w patterns on the headligh t domes of different two wheelers (HERO HONDA PASSION PLUS and BAJAJ PULSA R) wh ich influence the sta bility of the vehicle. The pressure distribution over the surface of the profile and the drag force are to be determined for various headlight dome orientations . This study helps in suggesting the suitable headlight dome profile that may reduce the drag force and effect of turbulence which in turn leads to the increase of vehic le stability. The results obtained during the simulat ion are to be validated by conducting the experiments on the scale down model of the headlight dome of HERO HONDA PASSION PLUS using Wind Tunnel test rig. The Co mputational Fluid Dynamics (CFD) tool was used to simu late the air flow pattern on the headlight dome in which boundary layer separation doesn't exist. The results obtained from the simulation are to be co mpared with the experimental results from the wind tunnel and the variation is to be found and that should be in the acceptable limit.
