摘要
针对水面舰船在不同海况下航行时的破损进水和航行轨迹变化,基于有限体积法(FVM)、VOF法、体积力法和重叠网格,应用STAR-CCM+软件,对一艘破损舰船在静水、迎浪和横浪海况下航行时的进水过程和航行轨迹进行了研究。研究结果表明,破损舰船在静水、迎浪和横浪中航行时的最大进水量比静水中无航速时分别增加了8.67%,6.86%和15.39%。在舰船破损后,其航行轨迹在静水中会向破损舷侧作重复圆周运动,在迎浪和横浪中会向波浪前进的方向作螺旋运动。破损舱室的进水量速率、进水量和航行轨迹随海况不同而发生变化,在横浪中的变化最为显著。研究结果可为破损舰船制定操纵方案和施救措施,以及后续航行安全提供参考。
This paper studies the flooding process and sailing trajectory of the well-known 5415 frigate hull in a damaged state under different sea conditions.Using the finite volume method(FVM),body-force method,VOF method,and overlapping grids,and with the assistance of the software STAR-CCM+,numerical simulations were conducted for the process of flooding and changes of sailing courses of the damaged frigate hull in still water,head seas,and beam seas respectively.The results showed that compared with the amount of water intake in still water at zero speed,the largest amounts of water intake under the still water,head seas,and beam seas at a non-zero speed was increased by 8.67%,6.86%and 15.39%respectively.The damaged frigate hull in still water at non-zero speed did circular motions toward the damaged side,while it did different spiral moving toward the wave directions in head seas and beam seas.The flooding speed,amount of water intake,and motion trajectory of the hull varied with different sea conditions,and the variation was most significant in beam seas.This study could provide some technical support to quick decision-making and rescue planning for damaged warships.
