【摘要】：將波能發(fā)電系統(tǒng)和防波堤結(jié)合起來會(huì)使發(fā)電系統(tǒng)具有成本上的優(yōu)勢(shì)，同時(shí)發(fā)電系統(tǒng)的建造，運(yùn)行，維護(hù)會(huì)十分的方便。 本文在對(duì)梳式防波堤進(jìn)行了穩(wěn)定性測(cè)試的基礎(chǔ)上，對(duì)該防波堤展開了波能發(fā)電裝置的設(shè)計(jì)和研究。 通過對(duì)國(guó)內(nèi)外已經(jīng)較為成熟的各種類型的波能發(fā)電技術(shù)的介紹和對(duì)比，確定了適合設(shè)置在本研究中防波堤上的波浪發(fā)電技術(shù)為振蕩水柱式和水力透平式。 利用計(jì)算流體力學(xué)軟件FLOW-3D建立了數(shù)值波浪水槽，通過調(diào)整，得到了和實(shí)驗(yàn)室水槽吻合較好的波浪條件。在設(shè)置好的數(shù)值波浪水槽中進(jìn)行了多組測(cè)試，確定了水力透平式波能發(fā)電裝置轉(zhuǎn)化能量效率最高的斷面，但是轉(zhuǎn)化效率較低。 通過物理模型試驗(yàn)對(duì)數(shù)值模型計(jì)算的最優(yōu)斷面進(jìn)行了驗(yàn)證，對(duì)轉(zhuǎn)化性能進(jìn)行了測(cè)試。兩維的數(shù)值模型導(dǎo)致數(shù)值模型較物理模型試驗(yàn)結(jié)果稍有區(qū)別，波能轉(zhuǎn)化率和數(shù)值模型計(jì)算的結(jié)果十分接近。不同周期波浪作用下的性能測(cè)試表明決定水力透平式波能轉(zhuǎn)換裝置轉(zhuǎn)化性能的主要參數(shù)是流體通過透流孔流線的長(zhǎng)短。不同水位條件下的性能測(cè)試表明，上部斜坡和波浪表面的相互作用對(duì)波能轉(zhuǎn)化也起到了至關(guān)重要的作用。 用數(shù)值模型對(duì)振蕩水柱式波能發(fā)電裝置進(jìn)行了設(shè)計(jì)和測(cè)試。通過自振分析得出氣室的開口位置。數(shù)值水槽測(cè)試結(jié)果表明，在相對(duì)開孔率保持不變的情況下，氣室寬度較小的模型轉(zhuǎn)化效率較高。振蕩水柱式波能發(fā)電裝置中水柱振蕩的幅度可以看作是波能轉(zhuǎn)化效率的一個(gè)指標(biāo)。
[Abstract]:The combination of wave power generation system and breakwater will make the power generation system have the advantage of cost, at the same time, the construction, operation and maintenance of the power generation system will be very convenient. Based on the stability test of the comb breakwater, the design and research of the wave power generation device are carried out in this paper. Through the introduction and comparison of various types of wave power generation technologies at home and abroad, it is determined that the wave power generation technologies suitable for the breakwater in this study are oscillatory water column type and hydraulic turbine type. The numerical wave flume was established by using the computational fluid dynamics software FLOW-3D, and the wave conditions which were in good agreement with the laboratory flume were obtained by adjusting the numerical wave flume. Several tests were carried out in a set of numerical wave flume to determine the section with the highest conversion energy efficiency of the hydraulic turbine wave power generation device, but the conversion efficiency was relatively low. The optimum section calculated by the numerical model is verified by the physical model test, and the conversion performance is tested. The two-dimension numerical model results in a slight difference between the numerical model and the physical model test results, and the wave energy conversion rate is very close to that of the numerical model. The experimental results show that the main parameter determining the conversion performance of the hydraulic turbine wave-energy converter is the length of the flow line through the permeable hole. The performance tests at different water levels show that the interaction between the upper slope and the wave surface also plays an important role in the wave energy conversion. A numerical model is used to design and test the oscillating water column wave energy generator. The opening position of the chamber is obtained by natural vibration analysis. The results of numerical flume test show that the conversion efficiency of the model with smaller chamber width is higher when the relative opening rate remains constant. The amplitude of water column oscillation can be regarded as an indicator of the efficiency of wave energy conversion.
