【摘要】：我国作为能源消费大国,随着能源形势的日益紧张,开发利用可再生能源成为解决当今能源问题的重中之重。我国作为海洋大国,海域辽阔、海岸线漫长,拥有丰富的海洋能资源。波浪能作为海洋能的重要组成部分,是目前国内外海洋研究的热点。波浪能还可与太阳能、风能联合开发,为偏远海岛、海洋开发活动提供所需的电力,同时还可以减少使用化石能源带来的经济和环境问题。目前各类波浪能发电装置层出不穷,越浪式波浪发电装置具有结构简单、建造和维护方便、整体稳定性高的优点,便于群体化、密集型开发,还可以与海岸线良好的结合。基于与防波堤结合的滑动挡板式越浪发电装置的结构形式,建立了该装置的简易模型。在波浪水槽中进行模型试验,研究了正向规则波入射,不同斜坡高度及不同水深越浪式波浪发电装置的受力规律。采用FLOW-3D软件进行数值模拟,通过对不同波高、不同波浪周期、极端工况进行数值模拟,得出不同波浪要素下斜坡的受力规律。并通过数值模拟,研究了滑动挡板式波能发电装置越浪斜坡所受波浪力与斜坡比的关系,通过对试验结果和模拟结果的对比分析得出:在波浪入射过程中传感器响应时间不同;越浪斜坡在波浪周期作用下所受波浪力的数值在一定范围内波动;斜坡在波浪作用下波浪要素条件不变时,斜坡受力与斜坡高度、试验水深有关,呈线性关系。试验结果表明斜坡夹角26°至34°之间时,越浪斜坡受力随着斜坡夹角的增加而减小。研究成果为防波堤兼滑动挡板式越浪发电装置结构的提供设计依据。
[Abstract]:As a large country of energy consumption, with the increasing tension of energy situation, the development and utilization of renewable energy has become the most important part of solving the energy problems. As a large sea country, China has a vast sea area and a long coastline. As an important part of ocean energy, wave energy is a hot spot of marine research at home and abroad. Wave energy can also be jointly developed with solar and wind energy for remote islands. Ocean development activities provide the electricity needed while reducing the economic and environmental problems associated with the use of fossil energy. At present, various types of wave power generation devices are emerging in an endless stream, and wave-surpassing wave power plants have a simple structure. Easy to build and maintain, high overall stability, easy to group, intensive development, but also can be well combined with the coastline. A simple model of the device was established. The model test was carried out in the wave flume, and the force law of the wave generating device with normal incident wave, different slope height and different water depth was studied. The numerical simulation was carried out by using FLOW-3D software. Through the numerical simulation of different wave heights, different wave periods and extreme working conditions, the force law of slope under different wave elements is obtained. The relationship between the wave force and the slope ratio of a sliding baffle type wave power generator over a wave slope is studied. Through the comparison and analysis of the experimental results and the simulation results, it is concluded that the response time of the sensor is different in the process of wave incident; The value of the wave force on the slope under the action of wave period fluctuates in a certain range, and the force on the slope is related to the height of the slope and the depth of the test water when the conditions of the wave elements are not changed under the action of the wave. The experimental results show that when the slope angle is between 26 掳and 34 掳, the force on the overtopping slope decreases with the increase of the angle of the slope. The research results provide the design basis for the structure of the breakwater and sliding baffle type surpassing power generating device.
