⚡Color Coding Vortices – Flapping Wing Propulsion 🎨 While aeroplanes rely on the steady motion of a wing to generate aerodynamic forces, animals use more intricate motions to propel themselves through fluids, both during swimming and flying. The flapping motions cause the surrounding air or water to swirl around the edges of the wing or fin, and manipulating these vortices is important for the forces generated. Of course, the flows around bird wings and fish fins are usually invisible to us, so we mimicked these types of motions in the laboratory and devised a way to fluorescently colour code the water flows created by a 3D-printed wing. The results from these experiments are shown in these videos, where one sees a beautiful dance between the red vortices generated at the front and the green ones generated at the back. 🌎 Source: https://lnkd.in/etnyXbUm 📥 Science News: https://lnkd.in/d7B7fqA #engineeredmind #science #technology #engineering #mechanicalengineering #physics #mathematics
