摘要

越浪式发电装置具有结构稳定、可靠性高等优点。在前人的研究基础上，对越浪式波能发电装置的模型进行了优化设计，通过模型实验研究了该波能发电装置在不同波况、不同干舷高度下对波能的俘获能力以及结构的受力情况。对越浪量的试验结果进行了无量纲分析，分别得出了越浪式模型装置的越浪量关于干舷高度和波高的指数函数拟合曲线，总结了两者对越浪量影响的普遍规律。通过对规则波和不规则波波浪作用下装置受力结果的归纳总结，探讨了波能装置波压力和浮托力变化的一般规律。本研究可为越浪式波能发电装置的研究提供参考依据，为波浪能的利用提供一定的参考价值。%The Overtopping Wave Energy Convertor (OWEC)has the advantages of high structural stability and reliability.Base on previous studies,this paper design a new op-timized OWEC model,the wave energy capture capability and structure stress status during different wave conditions and freeboard are investigated through model test of the OWEC.The exponential function fitting curve of the overtopping discharge on the free-board height and wave height are respectively obtained by nondimensionalization,and the universal laws of the two factors on wave overtopping is also given.According to the analysis for pressure results of the OWEC during the regular wave and irregular wave conditions,the general changing laws of the wave pressure and uplift of the OWEC is obtained.The results can provide some reference for further research on the OWEC and the utilization of the wave energy.
