Flow Field Analysis and Contour Detection of a Natural Owl Wing Using PIV Measurementsf this wing, which is known to be perfectly adapted to the requirements of silent flight. This wing model possesses the basic geometry of the barn owl wing. To understand the impact of the owl-based shape plus the owl-specific anatomic elements on the flow field and to further analyze the characteri

Development and Fabrication of Active Microstructures for Wave Control on Airfoilsajor origin of this transition are Tollmien-Schlichting (TS) waves. Similar to the dolphin’s skin, a system that is capable to dampen TS waves locally is proposed here. A surface wave can interfere destructively with TS waves and thus delay transition towards the edge of the airfoil. For this purpos

Learning from Dolphin Skin – Drag Reduction by Active Delay of Transition: Flow Control by Distributts is used as actuator in wind-tunnel experiments. Direct methods of damping Tollmien-Schlichting waves are compared to a biomimetic approach imitating the dampingmechanisms of a compliant skin. In both cases, model predictive control algorithms are applied to control the multi-bar actuator segments
