摘要
为研究复合帆在弧形帆与转筒帆形态时的不同效果,采用STAR-CCM+仿真软件和风洞实验,通过收集弧形帆和转筒帆在不同的工况下产生的升力与阻力数据、分析复合帆在不同风况下的最优几何形状.结果表明:在顺风条件下,弧形帆的有益效果最大,并且可根据风速风向调整攻角;在恶劣天气条件下,转筒帆能保证较小侧向力和风帆面积,有利于提高船舶安全性,对恶劣天气的适应性好,并能通过调整转速控制推力大小,控制性更好.
In order to study the different effects of composite sail in the shape of arc sail and rotary sail,STAR-CCM+simulation software and wind tunnel experiment were used.By collecting the lift and drag data generated by arc sail and rotary sail under different working conditions,the optimal geometric shape of composite sail under different wind conditions was analyzed.The results show that the arc sail has the greatest beneficial effect under the condition of downwind,and the angle of attack can be adjusted according to the wind speed and direction.In bad weather conditions,rotary sail can ensure smaller lateral force and sail area,which is beneficial to improve ship safety.It has good adaptability in bad weather,and can control the thrust by adjusting the speed,which has better controllability.
