Stabilization of Boundary-Layer Flows Subject to Crossflow Instability with the Aid of Suction
Basic experiments were performed in a flow that is subject to a pure crossflow instability in order to examine boundary layer stabilization through holes and slots. For suction rates that correspond to industrial requirements, the experiments and jointly performed receptivity and nonlinear PSE computations show that reducing the spanwise inhomogeneity of the suction and choosing a location of the suction area as far as possible downstream of the attachment line are the most important parameters in order to make extensive use of the stabilizing potential of boundary layer suction.
