title = "Modulated global mode of a controlled wake",
abstract = "The 3D properties of the B{\'e}nard von K{\'a}rm{\'a}n global mode of the wake behind a 2D bluff body are investigated in an experimental study when a smaller, circular control cylinder is placed in the wake. Previous investigations [1, 2, 3], have shown the influence of a small control cylinder on the global frequency of the wake. The main effect is related to the interaction of vorticity produced by the control cylinder with the vorticity created by the bluff body. However, for certain positions of control, the envelope of the local velocity signal shows a modulation of amplitude. The search in the span-wise direction has shown the effects of the control cylinder{\textquoteright}s presence on existence and location of the modulation.",
