A passive control, based on wall suction acting at the leading edge, is proposed to stabilize the vortex shedding from a flat plate at incidence. The correct suction amount is determined by a potential flow model where the large-scale vortical structures formed near the plate edges are represented by point vortices of variable intensity, and the wall suction by an adequately placed sink. We concentrate on the case of a plate that is broadside to the flow and show that the stabilization of the vortex wake can be obtained by simple passive backside suction. In such a case geometric shaping and passive suction have similar effects on the vortex Hamiltonian. The model predictions compare well with the results obtained by blob-vortex simulations, thus confirming the stabilization of the unsteady wake past the plate.
