Harnessing wind energy using a flapping aerofoil

这个实验项目将探索一种新的形式或可再生能源。水流中的结构（风、潮汐等）可以感受到各种形式的振动工程师们通常会试图抑制这些振动，以防止对结构造成损坏，但近年来，人们对利用这些振动产生可再生能源的兴趣越来越大。该项目将集中在一个被认为能够实现高效率的流致振动的有希望的案例上;一个经历“颤振”的翼型，最常见的与飞机机翼相关的大振幅振动。成功的候选人将设计一个可以在玛丽皇后大学的风洞设施中进行测试的设备，以测量扑动翼型的能量输出。流动可视化和流体力测量以及结构运动的组合将用于说明性能如何取决于各种流动条件和结构参数。玛丽女王大学工程与材料科学学院制造的低成本压电材料将用于开发发电原型设备。

This experimental project will explore a novel form or renewable energy. Structures in flow (wind, tidal etc.) can experience various forms of vibrations. Engineers have typically sought to suppress these vibrations to prevent damage to the structures, but in recent years have seen a growing interest in harnessing them to generate renewable energy. This project will focus on one promising case of flow-induced vibrations that is thought to be capable of achieving high efficiency; an airfoil experiencing 'flutter', large amplitude vibrations that are most commonly associated with airplane wings.The successful candidate will design a device that can be tested in the wind tunnel facilities at Queen Mary University to measure the energy output from a flapping airfoil. A combination of flow visualisation and measurements of the fluid forces and motion of the structure will be used to characterise how the performance depends on various flow conditions and structural parameters. Low-cost piezoelectric materials, manufactured within the School of Engineering and Materials Science at Queen Mary, will be used to develop a prototype device to generate power.
