Flow turning effect and laminar control by the 3D curvature of leading edge serrations from owl wing

Autor: Muthuramalingam, Muthukumar, Talboys, Edward, Wagner, Hermann, Bruecker, Christoph

This work describes a novel mechanism of laminar flow control of a backward swept wing with a comb-like leading edge device. It is inspired by the leading-edge comb on owl feathers and the special design of its barbs, resembling a cascade of complex

Upstream Shear Layer Stabilisation via Self-Oscillating Trailing Edge Flaplets

Autor: Talboys, Edward, Bruecker, Christoph

The flow around a symmetric aerofoil (NACA 0012) with an array of flexible flaplets attached to the trailing edge has been investigated at Reynolds numbers of 100,000 - 150,000 by using High-Speed Time-Resolved Particle Image Velocimetry (HS TR-PIV)
