| 摘 要： | 本文在分析伴流分数组成成分的基础上,指出对同一船型而言,伴流分数的量与雷诺数有关。雷诺数减少,则伴流分致增加,同时根据一些国家拖网渔船船模试验的资料进行分析,提出了拖网渔船的伴流估算公式,该式可适用于拖网渔船:自航与拖航两种工况的伴流分数估算。较准确估算拖网渔船不同工况下的伴流分数,对节能工作也是有意义的。

| Abstract: | In this paper, based upon the analysing of constituent component for wake fraction, the author points out that the quantity of wake fraction is relative with R_(N) number, the wake fraction will be increased when the R_(N) number is reduced. In mean while, based upon the experiment data of ship models for trawlers of some countries, the analyses is engaged, and that the calculation formula of trawler is suggested. This formula can apply to free running and trawling contdition. It is also useful for saving energy. If the wake fraction is calculated accurately for trawler under the different opreation conditions. |
