Abstract
The vibration of car mirror is caused by fluid-dynamic force that is dominated by the flow structures and the unsteady behavior of the vortex when a car travels at high speed. In this paper, the turbulent structure of the car mirror with grooves wake was experimentally investigated. The instantaneous velocity fields were measured using PIV technique at a Reynolds number of 6300. By examining instantaneous and mean streamlines, vorticity contours and Reynolds stresses, the wake structure of the car mirror with grooves was compared to the car mirror without grooves. It is found that the region of the reverse flow, the size of vortex and Reynolds stress were reduced by grooves.
