风帆助航渔船的稳性及经济性分析

摘要

Sail-assisted ship is an important way to save energy. The paper chooses a squid fishing vessel as research object, selecting NACA0006 sail and arc-shaped sail based on the characteristics of the ship, then using Fluent software to set up sail models, and numerically simulate air dynamic of these two kinds of sails. We can estimate energy-saving per year and the amount of reducing carbon dioxide emissions of the sail-assisted ships according to the results of software. By analysis the stability of sail-assisted squid fishing vessel, it is certain that sail-assisted squid fishing vessel is able to meet stability requirements, as long as reasonable installation and operation of sails.%风帆助航是船舶节能减排的重要途径.本文以1条鱿鱼钓船作为研究对象,根据该船的特点选择NACA0006型帆和圆弧型帆作为辅助风帆,然后利用Fluent软件建立所选风帆模型,对这2种风帆的空气动力性能进行数值模拟计算.根据软件的计算结果估算风帆助航时鱿鱼钓船的每年节油量以及所减少的二氧化碳排放量.通过对风帆助航鱿鱼钓船的稳性进行计算分析,可以确定只要合理地安装和操作风帆,风帆助航渔船是能满足稳性要求的.
