摘要在过去的三十年里，世界各地的一些研究人员开发了海洋能源装置。此外，设计用于测试这种装置的实验设施已变得越来越集中于产生多方向的、真实的波。特别是，位于爱丁堡大学的FloWave是世界上第一个在多方向圆形水箱中再现波浪和水流组合（包括恶劣设计条件）的海洋能源研究设施。在这项研究中，一个数值水槽模型的FloWave多向波池使用修改后的版本的DualSPHysics的图形处理单元。几何形状包括168个造波机桨，这些桨使用颗粒构造并作为固相处理。旋转角度数据分别施加在每个桨产生单色长峰规则/不规则波列和同心波奇点，包括波吸收。模型确定的表面高程的结果与实验结果总体一致，几个规则，不规则，同心波条件下成功地再现在一个多方向波盆。所提出的研究代表了第一次报告再现的多向波槽，和多向波，使用基于粒子的方法。为了证明未来的能力，数值模型也被应用到一个强大的流体-结构之间的相互作用波列和海上风力涡轮机结构与六个自由度作为进一步的工作。
ABSTRACT Several researchers around the world have developed ocean energy devices over the last three decades. Furthermore, experimental facilities designed to test such devices have become increasingly focused on the generation of multidirectional, realistic, waves. In particular, FloWave, located at the University of Edinburgh, is the first ocean energy research facility in the world to reproduce wave and current combinations including severe design conditions in a multidirectional circular water tank. In this study, a numerical water tank model was developed for the FloWave multidirectional wave basin using a modified version of DualSPHysics on graphics processing units. The geometry includes 168 wave-maker paddles that were constructed using particles and treated as a solid phase. Rotation angle data were individually imposed on each paddle to generate monochromatic long-crested regular/irregular wave trains and a concentric wave singularity including wave absorption. Model-determined surface elevation results were in overall agreement with the experimental results; several regular, irregular, and concentric wave conditions were successfully reproduced in a multidirectional wave basin. The presented research represents the first reported reproduction of a multidirectional wave tank, and multidirectional waves, using particle based methods. To demonstrate future capability, the numerical model was also applied to a strong fluid–structure interaction between wave trains and an offshore wind turbine structure with six degrees of freedom as a further work.
