【摘要】 为了促进开放海域海养殖装备智能化、无人值守化发展,解决离岸养殖装备自主供能以及安全防护问题,针对所提出的Savonius型(S型)桨叶捕能消波式浮式防波堤,建立二维波浪数值水池,搭建物理水槽试验系统和海试系统,通过仿真和试验研究系统在不同结构参数下的水动力学特性,分析探究相对间距、相对入水深度、波陡对系统捕能消波性能的影响.研究结果表明:该防波堤系统能同时进行捕能和消波,其捕能性能随着波陡的增加而增加,在周期1.6 s时捕能效果最好;消波性能随相对间距的增加而变好,透射系数为0.2～0.8,消波效果显著.系统捕能与消波性能存在相互影响,多数情况下两者不能同时达到最佳.海试运行测试验证了该型防波堤的捕能消波效果.更多还原

【Abstract】 An energy-capturing and wave-dissipating floating breakwater with Savonius type(S type) blade was proposed, in order to promote the intelligent and unattended development of marine aquaculture equipment in open sea area, and to solve the problems of independent energy supply and safety protection of offshore aquaculture equipment. A two-dimensional wave numerical pool was established, the physical tank test system and the sea test system were built. The hydrodynamic characteristics of the system under different structural parameters were studied by simulation and experiment, and the effects of relative spacing, relative depth of water entry and wave stepness on the energy capture and wave dissipation performance of the system were analyzed. Results showed that the breakwater system can simultaneously capture energy and eliminate waves, the energy capture performance of the breakwater system increased with the increase of wave steepness, the energy capture effect was the best when the period was 1.6 s, and the wave dissipation performance became better with the increase of relative spacing. The transmission coefficient fluctuated in the range of 0.2～0.8, and the wave dissipation effect was remarkable. In most cases, the energy capture and the wave dissipation performance of the system can not reach the best at the same time.The sea trial operation test verifies the energy capture and wave dissipation effect of the floating breakwater system.更多还原
