This proposal is for a pilot project to link EPSRC funded research expertise with applied sports research with a view to UK performance in the 2012 Olympics. In this project, we will investigate experimentally whether UK Sport needs to be concerned at potential performance gains in some sports resulting from the so-called Lotus Effect . In this effect hydrophobicity and topography are combined to create slippy super-water-repellent surfaces. Recent academic work on this type of surface has suggested that the no-slip boundary condition for simple liquids becomes relaxed and causes a finite slip length for water flowing over the surface. There have been claims in the literature of a reduction in flow resistance of around 15% attributed to a slip length of greater than 250 microns. Our project will review the literature for relevance to sport, review and interpret recent towing tank experiments by UK Sport, create a range of super-hydrophobic surfaces and provide specimens for testing by UK Sport.

该提案是一个试点项目，旨在将EPSRC资助的研究专业知识与应用体育研究联系起来，以期英国在2012年奥运会上的表现。在这个项目中，我们将通过实验调查英国体育是否需要关注所谓的莲花效应在某些运动中的潜在表现提升。在这种效果下，疏水性和地形结合在一起，形成了光滑的超级拒水表面。最近关于这类表面的学术研究表明，简单液体的无滑移边界条件变得松弛，并导致流过表面的水具有有限的滑移长度。在文献中有声称，由于滑移长度大于250微米，流动阻力减少了约15%。我们的项目将回顾与体育相关的文献，回顾和解释英国体育最近的拖曳水箱实验，创造一系列超疏水表面，并为英国体育提供测试样本。
