Shark skin is covered in denticles ... by acting as high-powered, low-profile vortex generators, the denticles on the airfoil significantly increased lift. "These shark-inspired vortex generators ...

But an ichthyologist at Harvard performed a study and found that Fastskin is “nothing like shark skin at all,” and that its surface properties ... called a leading-edge vortex, as the water ...

A team of evolutionary biologists and engineers have demonstrated a new structure inspired by shark skin that ... increased lift, acting as high-powered, low-profile vortex generators.

Harvard scientists have developed a new structure inspired by shark skin that could improve ... significantly increased lift, acting as high-powered, low-profile vortex generators.

Prior studies had shown that denticle ridges reduced friction drag by lifting turbulence vortices away from the shark skin surface, and such vortices are larger and farther away from the skin at ...

Lauder said: 'It’s nothing like shark skin at all. 'What we have shown conclusively is that the surface properties ... enhance this leading-edge vortex. So my hypothesis is that these structures ...

The riblets, as seen on the scales, or “denticles,” of a shark’s skin ... the majority of the riblet surface. As a whole, vortex translation across the skin surface is also reduced by ...

Next, the team 3D-printed the shapes on the surface ... new shark-inspired design, however, achieves a lift-to-drag ratio improvement of up to 323pc compared to an airfoil without vortex generators.

disturbing the flow of water over the surface to reduce the drag it experiences. However, existing research into the benefits of shark skin bothered Lauder, since much of it was based on shark ...
