Abstract: A drag reduction apparatus for reducing the aerodynamic drag on a bluff body with a blunt trailing edge caused by fluid flow characteristics at the wake of the bluff body, the drag reduction apparatus comprising: one or more control elements configured to be coupled to the bluff body and to move with respect to the bluff body, whereby the movement of the one or more control elements controls fluid flow at the wake of the bluff body to reduce the drag caused by fluid flow instabilities and environmental asymmetries.
