作为全球生产可再生电力的一部分，人们正在设计利用海浪和潮汐能量的设备。物理比例模型测试是该技术和其他技术开发过程中的重要组成部分。爱丁堡大学的FloWave海洋能源研究设施专门用于进行这些测试。在这里，可以产生多向波，结合圆形水箱中的水流，重现海洋的复杂性。这项研究是由该设施的商业需求推动的，旨在强调在受控环境中，在复杂条件下进行大规模测试可以学到什么。为了实现这一点，首先需要扩展这个新设施的特征。波浪的产生和反射在之前的项目中进行了评估。在这项工作中，在水箱的整个测试体积中进行流量测量，可以确定电流的空间和时间变化。波浪和电流以一种复杂的方式相互作用，通过在水箱中再现它们的方法使其更加复杂。评估了海流对流域波浪的影响。这包括他们之间有一个倾斜角度的病例，关于这一点很少发表。项目的另一部分解决了在FloWave等波流组合盆地进行测试时需要考虑的问题。•在许多对近海可再生能源感兴趣的地点，波浪受到水深的影响。考虑了不一致缩放深度的含义，并生成了设计图，以促进对潜在错误的理解和量化。•在FloWave，波浪是在水箱外部周围的静水中产生的。因此，开发并验证了一种工艺，以在中央测试区域与电流相互作用后产生所需的组合条件。•针对船舶、海上结构以及最近的可再生能源，有大量关于油罐测试的出版指南。我们对此进行了审查，并提出了一些建议，可以在FloWave等设施的更先进条件下进行测试。•开发了工具和指南，以突出客户在FloWave测试之前需要考虑的许多问题。其目的是通过突出潜在的知识差距和记录所做的决定来促进测试方案的规划。已经制作了流程图以图形方式表示这一点，并为客户提供了相应的问题清单，这些问题已在试点研究中试用。这项研究的结果被用来帮助FloWave提供学术和商业客户端测试。实验结果表明，电流条件下的测试面积为50m2，流量变化<10%，并探索了波流结合的可能条件。在设计客户端测试计划时非常重要的结果。
As part of a global drive to produce renewable electricity, devices are being designed to harness energy from the waves and tidal currents. Physical scale model testing is an important part of the development process for this and other technologies. The FloWave Ocean Energy Research Facility at The University of Edinburgh is designed to conduct these tests. Here it is possible to produce multi-directional waves combined with currents in the circular tank, re-creating the complexity of the ocean. The research was driven by commercial requirements of the facility, aiming to highlight what can be learnt from testing at scale with complex conditions in a controlled environment. To enable this, it was first necessary to extend the characterisation of this new facility. Wave generation and reflections were assessed in a previous project. In this work, flow measurements taken throughout the test volume of the tank, allowed spatial and temporal variations in the currents to be determined. Waves and currents interact in a complex manner, compounded by the method of reproducing them in a tank. The influence of currents on waves in the basin was assessed. This included cases with an oblique angle between them, on which little has been published. The other part of the project addressed issues to be considered when testing in a combined wave-current basin such as FloWave. • At many sites of interest for offshore renewable energy, waves are influenced by water depth. Implications of not scaling depth consistently were considered, and design diagrams produced to facilitate understanding and quantification of potential errors. • At FloWave, waves are generated in still water around the outside of the tank. A process was therefore developed and verified to produce the desired combined conditions in the central test area following their interaction with the current. • There is a wealth of published guidance on tank testing, for ships, offshore structures, and more recently renewable energy. This has been reviewed and suggestions offered to augment this by including testing in the more advanced conditions possible in a facility like FloWave. • Tools and guidance have been developed to highlight many of the issues to be considered by clients prior to testing at FloWave. This aims to facilitate planning of a test programme by highlighting potential knowledge gaps and recording decisions made. Flowcharts have been produced to represent this graphically, with a corresponding checklist of questions for clients, which have been trialled in a pilot study. Outputs from this research are being used to help deliver both academic and commercial client tests at FloWave. The test area in currents was shown to be >50m2 with <10% variation in flow, and the combined wave-current conditions possible have been explored. Results that are important when designing client test plans.
