03.3 - Basic Fluid Dynamics and Flow ControlRESOLVENT-BASED CONTROL OF STREAKS IN BOUNDARY LAYERSP.A.S. Nogueira¹, A.V.G. Cavalieri¹, A. Hanifi², D.S. Henningson²; ¹Instituto Tecnológico de Aeronáutica, Brazil ;²KTH Royal Institute of Technology, Sweden In the present work, we investigate efficient placement of sensors and actuators for closed-loop control of boundary-layer flows. This is done using a reduced-order model based on resolvent analysis, an approach that also allows us to analyse the sensitivity of the flow response to control. The focus of this work is on the flow cases where perturbation filed is dominated by streak. |
