【摘要】：振荡浮子式波浪能发电装置是一类重要波浪能利用设备。但是这类设备的单体功率较低,为提高总输出功率,阵列式开始出现并成为研究热点。阵列式是指将若干浮子按照一定规则排列在海域中,通过整流设备将所获取的能量进行整合,统一发电并利用。文中介绍的研究其目的就在于研究浮子阵列的布置方式。在研究过程中利用CFD软件FLOW3D进行三维数值模拟,获得了浮子在实际波况条件下的波浪场分布情况。通过多属性决策方法确定优选排列型式,计算空间尺度,并进行验证。实验结果表明:在实验条件下后方浮子应排列在前方浮子正后方(行列应垂直布置),同排和同列相邻浮子优选间距为6.9m。
[Abstract]:The oscillating float type wave energy generator is a kind of important wave energy utilization equipment, but the unit power of this kind of equipment is low, in order to increase the total output power, The array pattern begins to appear and becomes a research hotspot. Array type refers to arranging a number of floats in the sea area according to certain rules and integrating the acquired energy through rectifying equipment. The purpose of this paper is to study the arrangement of float array. In the course of the research, the three-dimensional numerical simulation is carried out by using CFD software FLOW3D. The wave field distribution of float under the condition of actual wave condition is obtained. The optimal arrangement pattern is determined by multi-attribute decision method, and the spatial scale is calculated. The experimental results show that the rear floats should be arranged directly behind the front floats under the experimental conditions (the row and column should be arranged vertically and the optimal selection distance of the adjacent floats in the same row and the same column is 6.9 m).
