Abstract
Experimental investigations aiming at the reduction of the aerodynamic drag of a 2D bluff body by closed-loop flow control are conducted. Pulsed suction at the rear end of the body has been applied. The controllers exploit measurements of the base pressure of the body since the base pressure correlates well with the drag. Disturbances in terms of changed oncoming flow conditions have been examined. Furthermore, a second 2D bluff body appearing in the wake of the first body disturbs the flow field. A model predictive and a robust model predictive controller have been tested successfully in experiments and are compared.
