| 摘 要： | 以船舶操纵水动力预报为研究背景,以无界流场势流理论为基础,采用边界元法,对目标Wigly船在斜航运动状态下的流场速度和转首力矩进行计算。分析了斜航时船舶周围流场的分布规律,研究了转首力矩随船舶漂角的变化规律。结果表明,该研究对预报斜航时船舶的运动规律具有较好的应用前景。

| Abstract: | The research on hydrodynamics of ship maneuverability based on the potential flow theory was presented.The velocity of flow field near the Wigly ship and the yawing moment of the ship when sailing with drift angle were calculated using boundary element method.The distributing of flow field near the sailing ship with drift angle was analyzed and variation of the yawing moment with the drift angle was studied.The results show that these researches adapt to prediction of ship movement with drift angle. |

| Keywords: | maneuverability boundary element method flow field hydrodynamics drift angle |
