【摘要】：海洋能作為一種新型可再生清潔能源,可為世界經(jīng)濟科持續(xù)發(fā)展作出巨大貢獻,海洋養(yǎng)殖資源對推動社會發(fā)展的剛性物質(zhì)需求和糧食供應(yīng)提供了必要的保障�，F(xiàn)有海水生態(tài)養(yǎng)殖業(yè)多集中在港灣,大多采用機械化養(yǎng)殖方式,但港灣養(yǎng)殖如今已趨于飽和,且海洋生態(tài)養(yǎng)殖除了自身在結(jié)構(gòu)設(shè)計、抗惡劣養(yǎng)殖環(huán)境性能、抗擊風(fēng)浪沖擊性能等方面有缺陷,還存有養(yǎng)殖輔助裝備供能較難等現(xiàn)實問題,針對這些問題本文主要研究了以下內(nèi)容。分析海水生態(tài)養(yǎng)殖裝備適用的實際海況,基于海洋環(huán)境物理學(xué)、海水運動特性、海洋水動力學(xué)等理論基礎(chǔ),重點研究實際海域中海浪、海流及潮流耦合作用機理,建立有效而準確的耦合流體模型。根據(jù)近海生態(tài)養(yǎng)殖海域?qū)嶋H情況,結(jié)合不同結(jié)構(gòu)形式在耦合流體中的運動、受力及捕能效率,綜合分析傳統(tǒng)防波堤及海洋能捕獲發(fā)電系統(tǒng),提出新型的消波減流柔性防護系統(tǒng),確定了防護系統(tǒng)主要由浮式HDPE管道及阻力型海洋能捕獲裝置組成,并理論分析了柔性防護系統(tǒng)的消流效果及捕能效率�；�于模型相似準則,建立海洋能捕獲葉輪的三維模型,并進行CFD模型仿真計算,通過實際實驗室水池水動力測試,并構(gòu)建相應(yīng)的潮流能捕獲測試實驗系統(tǒng),通過對實驗結(jié)果的對比分析優(yōu)化柔性防護系統(tǒng)。
[Abstract]:As a new type of renewable clean energy, oceanic energy can make a great contribution to the sustainable development of the World Economic Section. Marine aquaculture resources to promote the social development of rigid material demand and food supply to provide the necessary protection. The existing marine ecological aquaculture mostly concentrated in the harbour, most of them adopt mechanized aquaculture. But the harbor culture has become saturated now, and the marine ecological culture has defects in the aspects of structure design, anti-bad environment performance, resisting the impact of wind and waves, and so on. There are still some practical problems such as the difficulty of energy supply of aquaculture auxiliary equipment. In view of these problems, the following contents are mainly studied in this paper. The actual sea condition of marine ecological aquaculture equipment is analyzed, based on marine environmental physics. Based on the characteristics of sea water motion and marine hydrodynamics, the coupling mechanism of ocean wave, current and tidal current in actual sea area is studied. To establish an effective and accurate coupled fluid model. According to the actual situation of offshore ecological culture sea area, combined with the different structural forms in the coupled fluid movement, force and energy capture efficiency. Based on the analysis of traditional breakwater and marine energy capture power generation system, a new flexible protection system for wave dissipation and current reduction is proposed. It is determined that the protection system is mainly composed of floating HDPE pipeline and resistance type oceanic energy capture device. Based on the model similarity criterion, the three-dimensional model of ocean energy capture impeller is established, and the simulation calculation of CFD model is carried out. Based on the hydrodynamic test of the laboratory pool and the corresponding tidal current energy capture test system, the flexible protection system is optimized by comparing and analyzing the experimental results.
