Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective of reducing drag by adhering a compliant skin to the surface. While the correct choice of compliance relies upon understanding very complex flow-structure dynamics, the resulting technology is simple, robust and has low capital and maintenance costs. Clearly, drag reduction reduces fuel costs and lower fuel consumption is environmentally beneficial.

湍流的特征是表面上无序的波动，通过产生增加的摩擦力或阻力来阻碍物体通过流体的前进。使用一种新型的流体流动模拟，该项目将产生对车辆表面流动中湍流的深入了解，无论是船舶，汽车，飞机还是管道内，其技术目标是通过将柔性蒙皮粘附到表面来减少阻力。虽然顺应性的正确选择依赖于对非常复杂的流动结构动力学的理解，但由此产生的技术简单、稳健，并且资本和维护成本低。显然，减阻降低了燃料成本，降低燃料消耗对环境有利。
