Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels, reducing material and manufacturing costs without compromise to safety and performance - an immense benefit for the myriad engineered products or structures that feature flow over a deformable surface.

流体流动产生的压力可以使结构的表面变形或使其振动；一个极端的例子是飘扬的旗帜。车辆外部面板的流动引起的振动会造成损坏、噪音，并对性能产生不利影响。这个项目将开发一种全新的方法来分析这些相互作用。该方法的多功能性和完整性允许面板设计的阶梯式变化，在不影响安全性和性能的情况下减少材料和制造成本-对于无数具有可变形表面流动特征的工程产品或结构来说，这是一个巨大的好处。
