This PhD research aims to develop an optimised design of a Multiple Wave Absorber Platform (MWAP) via a combined numerical and physical modelling approach. The device architecture is informed through industrial/commercial collaboration with a world-leading body (Wave Energy Scotland) and will be based on a differential pressure device. This work will aim to achieve a step-change in WEC energy density through the co-location of multiple WECs on a single platform. This requires the application of a co-design approach to understand the design interactions between station-keeping, WEC hydrodynamic interactions (layout), and WEC control in particular. There are unknown questions on the benefits or deficits of using a coupled pneumatic spring system on this class of pressure differential WECs, an understanding of which is required to drive these design decisions. This work will look to close the numerical simulation to tank testing gap for the MWAP concept, providing a more mature design and knowledge to drive future design iterations.The work builds upon past collaborations on the MWAP concept undertaken with WES through my position at FloWave. The intention is to leverage the hardware (which I have been heavily involved with at design stage) to answer the more fundamental research questions excluded from the short test programmes undertaken to date. In particular, the work is to explore the techniques required to achieve lowered levelised cost of energy through higher energy density (co-located devices), shared station keeping systems, and common grid connection infrastructure. Balancing the demands of power take off optimisation, system mass and performance will likely require a co-design approach, while fundamental questions remain on the "simulation to tank gap" when comparing numerical and physical modelling design tools. Assessing this gap in the context of the MWAP platform is a central pillar of this proposed research.

这项博士研究旨在通过数值模拟和物理模拟相结合的方法来开发多波吸收平台(MWAP)的优化设计。该设备的架构是通过与世界领先的机构(苏格兰浪潮能源公司)的工业/商业合作来提供信息的，并将基于差压设备。这项工作的目的是通过将多个WEC共置在一个平台上来实现WEC能量密度的阶跃变化。这需要应用合作设计方法来理解站位保持、WEC水动力相互作用(布局)、特别是WEC控制之间的设计相互作用。在这类压差WEC上使用耦合气动弹簧系统的好处或缺点尚不清楚，需要了解这一点才能做出这些设计决策。这项工作将寻求弥合MWAP概念的数值模拟到水箱测试的差距，提供更成熟的设计和知识来推动未来的设计迭代。这项工作建立在过去通过我在FloWave的职位与WES进行的MWAP概念合作的基础上。这样做的目的是利用硬件(我在设计阶段就大量参与了这方面的工作)来回答迄今已开展的短期测试计划中排除的更基本的研究问题。特别是，这项工作是探索通过更高的能量密度(共置设备)、共享站保持系统和公共电网连接基础设施来实现更低的水平能源成本所需的技术。平衡动力起飞优化、系统质量和性能的需求可能需要一种联合设计方法，而在比较数值和物理模型设计工具时，基本问题仍然是“模拟与坦克之间的差距”。在MWAP平台的背景下评估这一差距是这项拟议研究的中心支柱。
