摘要:

针对南海不同波浪要素条件下波浪滑翔机翼板参数设计的问题进行研究。基于欧洲中尺度天气预报中心大气和海洋全球再分析数据集(ERA5), 对南海不同季节以及台风经过时的波高波周期进行统计。并利用FLUENT软件研究南海不同波浪要素条件下翼板最大偏转角度、转轴位置以及翼板间距对波浪滑翔机水下翼板平均推力的影响。仿真结果表明, 波高越大, 翼板最大偏转角度也应相应增大, 才能保证翼板获得更大的推力; 在南海波浪要素条件下, 翼板转轴位置选取在翼板前端1/5处较佳; 适当增加翼板间距能够提高翼板获得的推力。通过对翼板被动摆动进行仿真, 得到了翼板在不同参数设置下产生的推力, 为波浪滑翔机翼板设计提供参考。

关键词: 波浪滑翔机, 最大偏转角度, 转轴位置, 翼板间距

Abstract:

In view of different wave height and period in the South China Sea, the design of Wave Glider wing parameters is studied to obtain greater thrust. Based on the reanalysis data set of ERA5, we provide statistics on the wave height and wave period of different seasons and induced by one typhoon in the South China Sea. In addition, the software FLUENT is used to study the influence of the maximum limit angle, the position of rotating axis and the spacing of the wings. The simulation results show that the larger the wave height, the larger the maximum limit angle should be in order to ensure that the wings can get more thrust. Under the conditions of wave height and period in the South China Sea, it is better to select 1/5 of the front of the wing as the position of rotating axis. Increasing the spacing of the wings properly can improve the thrust. By simulating the flapping wings, the thrust generated by the wings under different parameters is obtained, which provides a reference for the design of the wings.

Key words: Wave Glider, maximum limit angle, position of rotating axis, spacing of the wings
