The vortices generated behind a simplified vehicle induce presssure forces at the back wall that contribute to a significant part of the drag coefficient. The study shows the strong relationship between the distance of the vortices to the back wall and these pressure forces. In particular, control process can modify the trajectory of the vortices to accelerate their removal from the wall and consequently reduce the drag coefficient.
