Description
Benjamin Kellum Cooper and co-authors test a shark-inspired surface that cuts drag in a 2025 study. Passive skins can lower drag in wall-bounded flows without burning power. Earlier simulations over a bump found reverse flow under shark denticle crowns, which pushed back against the stream.
Their engineered surface, a porous layer with one-way character, copies the denticle's key geometry. Direct simulations of turbulent channel flow test it at strong turbulence levels. Wind tunnel trials with printed samples check the same effect in air. Thrust from hidden reverse flow is a strange, promising trick. Ships and planes both pay heavily for drag, so even small cuts matter.
