Fluid-structural interactions in high-speed flows

本项目旨在进行实验测量高超声速流动中的流固耦合。这项工作将提高模拟工具的准确性，这些工具是帮助工业设计更具结构效率和更坚固的高速车辆所急需的工具。这些工具将反过来被用来揭示流体-结构相互作用的潜在物理，并确定驱动参数的相对重要性。准确预测受这些流体-结构相互作用影响的结构部件的行为和寿命，在这些相互作用中，由局部流场引起的结构变形反过来可以影响该流场。这种耦合可能会导致损坏甚至灾难性的结构故障，因此必须开发坚固的设计工具来避免这种情况。

This project aims to perform experiments to measure fluid-structure interaction in hypersonic flows. The work will improve the accuracy of simulation tools that are urgently required to aid industry in the design of more structurally efficient and robust high-speed vehicles. These tools will in turn be used to reveal the underlying physics of the fluid-structure interactions and establish the relative significance of the driving parameters. Accurate prediction of the behaviour and lifetime of structural components subject to these fluid-structural interactions, in which the deformation of the structure induced by the local flow field, can in turn influence this flow field. This coupling can result in damage or even catastrophic structural failure and thus robust design tools must be developed to avoid this.
