| 摘 要： | 我国作业的众多渔船中,拖网渔船占了多数。为了响应国家节能减排政策,故采取安装合适的球鼻艏以起到减少阻力的作用。文中采用CFD技术,在球鼻艏伸出长度的变化上对拖网渔船进行阻力的比较研究,从中得到适当的球鼻艏使得拖网渔船在设计航速下得到较好的减阻节能效果。

| Abstract: | Trawlers are of majority among the fishing boats operating in China. According to national policy of Energy Saving and Emission Reduction,proper bulbous bow has been installed to reduce resistance. The resistances of different bulbous bow lengths for a trawler are compared by CFD technology,it is concluded that proper bulbous bow allows the trawler to get a resistance reduction and energy saving at the design speed. |
