Nonlinear hydrodynamic loadings on Floating Offshore Wind Turbine

在过去的几年里，无人机已经扩展了完成大量和多样化的民用和军事应用和任务的能力。然而，无人机技术大规模应用的一个关键限制是设备的耐用性。本研究旨在通过进一步探索蒲公英种子激发飞行等被动推进模式的机理，提高小型无人机的续航能力。特别是，将从实验和数值两个层面研究简单几何结构和非定常流动条件下的流固耦合和其他气动特性，以发展关于被动推进模式的新的基础知识。随后，开发的技术将扩展到设计和分析低阻能量收集装置，为零能和低能运输提供新的工程解决方案。

Over the past few years, drone has extended the ability for accomplishing vast and diverse civilian and military applications and missions. However, a key limitation of the large-scale application of drone-based techniques is the endurance of the device. This research aims to enhance the endurance of small drones by further exploring the mechanisms of dandelion seed inspired flight and other passive propulsion modes. Particularly, investigations on the fluid-structure interaction and other aerodynamics characteris-tics with simple geometries and unsteady flow conditions will be carried out at both experimental and numerical levels to develop novel and fundamental knowledge about passive propulsion mode. Subsequently, the developed technique will be extended to design and analyse low-drag energy harvesting devices, contributing to new engineering solutions for zero-energy and low-energy transportation.
