Development of a lift based wave energy converter (WEC)

本项目中提出的基于升力的波能转换器(WEC)使用相对的水翼绕固定点旋转，通过整个海浪振荡过程中不断变化的流体颗粒速度来产生升力。这项技术的潜力是由贝尔法斯特-LiftWEC女王大学领导的H2020项目财团的主题。H2020 LiftWEC项目的期限为三年，技术开发准备级别为1-3。在此期间，将对几个概念进行数值评估，并将使用一些物理模型(2D和3D)进行验证。博士项目旨在通过数值和实验室规模的实验评估，探索基于Lift的WEC概念的可行性，并加深对该概念的理解。这一目标可以分解为几个目标；包括验证概念分析模型的实验测试。参数研究将分析子系统设计变量(如叶片、旋翼展开系数)对性能的贡献。该项目将增进对基于升力的波能转换器的流体力学的基本了解，并确定这项技术开发中的知识差距。与EPSRC的目标保持一致：-多产的国家--新型波能转换器的成功开发将在英国创造作为可再生能源技术领先者的技术和制造角色。-有弹性的国家-英国可再生能源组合的多样化将增加可再生能源在取代碳基能源发电方面的渗透率-健康国家-一种新的清洁能源发电来源减少英国对化石燃料发电的依赖，提高空气质量。

The lift-based wave energy converter (WEC) proposed in this project uses opposing hydrofoils rotating around a fixed point to generate lift force from the varying fluid particle velocities present throughout the oscillation of ocean waves. The potential of this technology is the subject of a H2020 project consortium led by Queen's University Belfast - LiftWEC. The H2020 LiftWEC project is limited to three years and technology development readiness levels of 1-3. During this period several concepts will be assessed numerically, and some physical models (2D and 3D) will be used for validation. The PhD project aims to explore the feasibility, and develop understanding, of a lift-based WEC concept through numerical and lab scale experimental assessment. This aim can be broken down into a few objectives; including experimental testing to validate analytical models of the concept. A parametric study will analyse the performance contribution of subsystem design variables (such as blades, rotor deployment factors). The project will improve fundamental understanding of the hydrodynamics of lift-based wave energy converters and identify knowledge gaps in the development of this technology. Alignment to the goals of the EPSRC: - Productive Nation - The successful development of a novel Wave Energy Converter will create technical and manufacturing roles in the UK as a leader of renewable energy technology. - Resilient Nation - Diversifying the UK's renewable energy portfolio will increase renewable energy penetration in replacing carbon-based energy generation - Healthy Nation - A new source of clean energy generation reduces the UK's reliance on fossil fuels to generate power, increasing air quality.
