Nature Research Highlights, Fluid dynamics: Slip and slide, Nature 454, 920
A paper recently published by Prof. Chang-Hwan Choi and his colleagues at UCLA (Phys. Rev. Lett. 101, 064501 (2008)) has also been selected as Research Highlights in Nature (Nature 454, 920). Prof. Chang-Hwan Choi and his colleagues created textured surfaces with micrometre-scale grooves and posts. On these, fluids can slip past friction-free for tiny distances, coasting on the pockets of air between the grooves or posts. They report a slip length for water almost ten times longer than previously achieved — long enough to show that engineered surfaces can significantly reduce drag in fluid systems including macroscale flows.
