【摘要】：随着经济的日益增长,能源的消耗也在不断增加,但化石燃料的枯竭,使各国开始把目光转向清洁的可再生能源。目前可替代清洁可再生能源主要有风能、太阳能、海洋能,而海洋能因其能量储量巨大,具有较高的开发可行性和潜在的经济效益,所以海洋能开发得到各国的青睐,随着海洋工程的建造,海洋开发的问题随之而来。如我们开发的漂浮式波浪发电装置,除了设计波浪捕获结构及其系统的问题,其中还有海洋对波能发电装置相互作用的问题,第一,波浪发电装置在水中的受力问题,由于没有解决好波浪力问题导致很多装置在海上经不起风浪而破坏；第二,海水腐蚀和海生物附着等问题都是现在海洋工程发展的障碍；由于海水腐蚀和海生物附着可通过在设计时增加的裕度加以弥补,所以当务之急是解决海上工程在海洋中的受力问题；本论文以单体漂浮式波浪发电装置在水中受力进行如下研究。第一,根据不同海况,在真实的海面上通过收集波浪发电装置的发电功率,并根据发电功率计算出浮筒受力情况。第二,根据不同的浮筒尺寸,不同的波高、波周期对波浪装置作用力影响进行模拟计算,软件基于连续方程和N-S方程作为控制方程,进行迭代来计算模拟浮筒的波浪受力。第三,通过实验和模拟数据对比分析,分析出模拟方式计算浮筒受力的准确性。
[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.
