摘要
船首侧推孔是在船首开一个贯穿船体的槽道,在其中装设螺旋桨,对船体产生侧向推力。槽道式艏侧推力器在零航速下能产生较大的侧向推力,但随航速增加,它产生的有效侧推力将显著下降。论文通过数值分析方法,模拟、分析球鼻艏船型船首侧推孔推力减缩的产生原因及其影响因素,为船首侧推器设计提供参考基础。
The bow thruster hole is a tunnel through the hull at the bow of the ship,where the tunnel thruster is installed.Large lateral thrust can be induced by the tunnel thruster when the speed of the ship is zero.With the increase of the ship speed,the effective thrust produced by the tunnel thruster decreases significantly.In the present paper,the cause and influencing factors of thrust loss for the tunnel thruster of the ship with a bulbous bow is studied with the numerical method.The results of numerical analysis are valuable for design of the bow tunnel thruster.
