| 摘 要： | 采用边界元方法对8301双尾船、HS80高速客船以及大径深比FT8601推轮共3艘内河双桨船型的势伴流分数进行了计算，探讨了势伴流占总伴流的比例以及桨盘处势伴流的分布规律，得出了一些初步结论。结果表明双桨船势伴流分数占总伴流分数的比例并不大，因此若用预估单桨船的伴流分数公式来预估双桨船是不可行的。

| Abstract: | The boundary element method has been used in this paper to calculate the potential wake fraction of the 8301 twin-stern ship，the HS80 high speed passenger ship and large diameter-to-draft ratio FT8601 pushboat. By calculation,the paper discussed the potential wake's proportion of the total wake and the potential wake's regularities on the propeller disk. From these discusses, some conclusions are obtained and show that the potential wake's proportion of the total wake for twin-propeller ship is not remarkable. Therefore,it is not available to predict the twin-propeller ship's properties with the calculation method available for the single-propeller ship. |
