Flow turning effect and laminar control by the 3D curvature of leading edge serrations from owl wing
Muthukumar Muthuramalingam, Edward Talboys, Hermann Wagner +1
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…
Transition Delay Using Biomimetic Fish Scale Arrays
Muthukumar Muthuramalingam, Dominik. K. Puckert, Ulrich Rist +1
Aquatic animals have developed effective strategies to reduce their body drag over a long period of time. In this work, the influence of the scales of fish on the laminar-to-turbul…
Streak formation in flow over Biomimetic Fish Scale Arrays
Muthukumar Muthuramalingam, Leo S. Villemin, Christoph Bruecker
The surface topology of the scale pattern from the European Sea Bass (Dicentrarchus labrax ) was measured using a digital microscope and geometrically reconstructed using Computer…
Seal and Sea lion Whiskers Detect Slips of Vortices Similar as Rats Sense Textures
Muthukumar Muthuramalingam, Christoph Bruecker
Pinnipeds like seals and sea lions use their whiskers in hunting their prey in dark and turbid conditions. There is no theoretical model or a hypothesis to explain the interaction…
