【摘要】：隨著經(jīng)濟(jì)的日益增長,能源的消耗也在不斷增加,但化石燃料的枯竭,使各國開始把目光轉(zhuǎn)向清潔的可再生能源。目前可替代清潔可再生能源主要有風(fēng)能、太陽能、海洋能,而海洋能因其能量儲(chǔ)量巨大,具有較高的開發(fā)可行性和潛在的經(jīng)濟(jì)效益,所以海洋能開發(fā)得到各國的青睞,隨著海洋工程的建造,海洋開發(fā)的問題隨之而來。如我們開發(fā)的漂浮式波浪發(fā)電裝置,除了設(shè)計(jì)波浪捕獲結(jié)構(gòu)及其系統(tǒng)的問題,其中還有海洋對(duì)波能發(fā)電裝置相互作用的問題,第一,波浪發(fā)電裝置在水中的受力問題,由于沒有解決好波浪力問題導(dǎo)致很多裝置在海上經(jīng)不起風(fēng)浪而破壞；第二,海水腐蝕和海生物附著等問題都是現(xiàn)在海洋工程發(fā)展的障礙；由于海水腐蝕和海生物附著可通過在設(shè)計(jì)時(shí)增加的裕度加以彌補(bǔ),所以當(dāng)務(wù)之急是解決海上工程在海洋中的受力問題；本論文以單體漂浮式波浪發(fā)電裝置在水中受力進(jìn)行如下研究。 第一,根據(jù)不同海況,在真實(shí)的海面上通過收集波浪發(fā)電裝置的發(fā)電功率,并根據(jù)發(fā)電功率計(jì)算出浮筒受力情況。 第二,根據(jù)不同的浮筒尺寸,不同的波高、波周期對(duì)波浪裝置作用力影響進(jìn)行模擬計(jì)算,軟件基于連續(xù)方程和N-S方程作為控制方程,進(jìn)行迭代來計(jì)算模擬浮筒的波浪受力。 第三,通過實(shí)驗(yàn)和模擬數(shù)據(jù)對(duì)比分析,分析出模擬方式計(jì)算浮筒受力的準(zhǔn)確性。
[Abstract]:With the economic growth, energy consumption is also increasing, but the depletion of fossil fuels makes countries begin to focus on clean renewable energy.At present, the main alternatives to clean and renewable energy are wind, solar, oceanic energy, and oceanic energy, because of its huge energy reserves, high feasibility of development and potential economic benefits, so marine energy development has been favored by all countries.With the construction of marine engineering, the problem of ocean development follows.For example, the floating wave power generation device that we developed, in addition to the design of wave capture structures and their systems, there is also the problem of ocean interaction with wave power generation devices. First, the force of wave power generation devices in water.Because of the failure to solve the problem of wave force, many devices can not withstand the wind and waves at sea, second, the problems of seawater corrosion and marine biological attachment are the obstacles to the development of marine engineering.Since seawater corrosion and marine biological attachment can be compensated by increasing the margin in the design, it is urgent to solve the stress problem of marine engineering in the ocean.In this paper, the single floating wave power generation device in the water force is studied as follows.Firstly, according to different sea conditions, the power of wave generator is collected on the real sea, and the force of buoy is calculated according to the power.Secondly, according to the different size of buoy, different wave height and wave period, the wave force is simulated. The software is based on the continuous equation and N-S equation as the governing equation, and iterates to calculate the wave force of the simulated buoy.Thirdly, the accuracy of the simulation method to calculate the force of buoy is analyzed by comparing the experimental data with the simulation data.
