摘要
简述了摆动叶片式波浪能发电装置的结构和工作原理,结合波浪力学和浅水波理论对摆动叶片进行理论分析,推导出俘获效率公式。为了分析装置的性能,采用Fluent软件仿真的方法,分析了摆角和波高参数对装置的水动力学性能的影响,提出最佳摆角概念,并研究了最佳摆角与波高的关系。研究结果表明:装置的俘获效率随着摆角的增大先增大后减小;随着波高的增加,装置的俘获效率在增加,研究结果为后期装置的试验提供了理论依据。
The structure and working principle of the oscillating blade - type wave energy power generation device were briefly introduced, and the wave mechanics and the shallow water wave theory were used to theoretically analyze the oscillating blade, then the capture efficiency formula was derived. In order to investigate the performance of the device, the effects of the swing angle and wave height parameters on the hydrodynamic performance of the device was analyzed by using the Fluent simulation software, and the concept of optimal swing angle was proposed, meanwhile, the relationship between the optimum swing angle and wave height was studied. The experimental results showed that, the capture efficiency of the device first increased and then decreased with the increase of the swing angle, and increased with the increase of the wave height. The research provided a theoretical basis for the later device experiments.
