In this paper, the effect of rear body shape on the wake structure behind vehicle and on its aerodynamic characteristics is clarified. Three different rear body shapes, with the same front and center body shape, are used. The flow behavior in the wake is observed by flow visualization using Digital Image Processing and numerical results. The authors obtained results that the aerodynamic characteristics of vehicles strongly depend on the behavior of the wake.
