论文摘要
淹没的箔可以将波能量直接转换为推力，这可能用于绿色海洋推进。这项研究使用内部开发的新计算流体动力学（CFD）框架分析了波浪诱导的液压推进。最初针对一些基准的问题验证了数值模型，然后用于对波诱导的拍打液压推进的数值研究。从涡流流图案中可以观察到阻力和推力之间的过渡。音高刚度和其他物理参数是第一次未二素化。为未来的绿色海洋系统设计提供了最佳波浪条件和最佳音高刚度。
Submerged flapping foils can convert wave energy directly into thrust, which could be potentially utilised for green marine propulsion. This study analyses the wave-induced flapping hydrofoil propulsion using an in-house developed, new computational fluid dynamics (CFD) framework. The numerical model was initially validated against a few benchmarked problems and then used for the numerical investigation of wave-induced flapping hydrofoil propulsion. The transition between drag and thrust can be observed from the vortex flow pattern. The pitch stiffness and other physical parameter were non-dimensionalised for the first time. The optimal wave conditions and the optimal pitch stiffness are given for the future green marine system design.
