Abstract
The aerodynamic noise and drag are associated with the flow structures and the unsteady behavior of the vortex causes the wind noise. However, litter attention has been paid to the complex vortical structures around externally mounted car mirror from the measured data. In this paper the turbulent structure of mirror wake has been experimentally investigated. The instantaneous velocity fields were measured using PIV technique at Reynolds number of 5900. Then, the wavelet-based vector multiresolution analysis was applied to the postprocessing of PIV results for identifying the multiscale turbulent structures of a car mirror wake. The intermediate and small-scale vortices embedded within the large scale vortices were separated and visualized.
