| 摘 要： | 驼背鲸鳍的前缘突出部有利于鳍上的升力提升.提出了一种模仿驼背鲸前鳍的减摇鳍,这种鳍型的前缘有正弦形的突出部.借助计算流体力学软件FLUENT,对这种模仿驼背鲸前鳍的新型鳍型进行了数值模拟流场计算,并与相同几何尺寸的标准NACA0015减摇鳍所测得的水池实验数据进行了对比,发现采用了前缘有圆形突出部设计的新型减摇鳍在相同条件下能提供更多的升力.对升力的增加机理进行了简要的分析.

| Abstract: | The fins of humpback whale with tubercles of the sine can enhance the life. In this theme, a new fin stabilizer which imitates the humback whale with the sine tubercles the leading edge is described with the help of FLUENT software, numerical simulation of the flow field on this new fin stibilizer is carried out and compared with experimental date of NACA0015fin stabilizer with the same geometric, the results show that more lift can be provided by the new fin stabilizer with rounded tubercles in the leading edge. |
