The aim of this project is to gain a physical understanding of the process of turbulence in fluid motion, focusing on boundary layers adjacent to the surface of bodies, such as submarines and turbines. As turbulence is of fundamental importance in many engineering tasks, developing our understanding of the mechanisms involved will lead to progress in many areas. For example, accurate prediction of drag on vehicles, aircraft and ships, resulting in reductions in fuel consumption. The wind tunnel used in this project is the largest of its type in the world, enabling pioneering experiments to be undertaken which will extend our understanding of the physics of turbulence for applied flows.

该项目的目的是对流体运动中的湍流过程进行物理理解，重点关注与物体表面相邻的边界层，例如潜艇和涡轮机。由于湍流在许多工程任务中具有根本的重要性，因此发展我们对所涉及机制的理解将导致许多领域的进展。 例如，准确预测车辆、飞机和船舶的阻力，从而减少燃料消耗。该项目中使用的风洞是世界上同类风洞中最大的，可以进行开创性的实验，这将扩展我们对应用流湍流物理学的理解。
