Wall turbulence is a critically important phenomenon for any system where fluid flows past an object. Wall turbulence is responsible for 90 per cent of the drag experienced by a large crude tanker, to give just one example. This project aims to investigate novel ways to control wall turbulence by exploiting the presence of recently-discovered large-scale structures. This will lead to significant reductions in the drag and fuel burnt by transport vehicles.

壁湍流对于任何流体流过物体的系统都是一种极其重要的现象。举一个例子，大型原油油轮所受阻力的90%是由壁湍流造成的。该项目旨在研究通过利用最近发现的大尺度结构来控制壁湍流的新方法。这将大大减少运输车辆的阻力和燃料消耗。
