破损船舶在波浪中的浸水是一个复杂的过程，往往伴随着船舶船体的运动而发生内部和外部的液体运动。为了提高船舶浸水过程中运动的预报精度，对破损船舶在横浪中的动力响应进行了研究，建立了光滑粒子流体动力学（SPH）模型，该模型考虑了完好舱室和破损舱室的内部晃荡以及外部波浪等多种因素的耦合作用。建立了具有完全匹配层吸收边界条件的数值波浪水槽，并通过实验验证了数值波浪水槽的有效性。重点研究了破损开孔尺寸、开孔相对位置、入射波和液体载荷条件对破损船舶在规则横浪中动力响应的影响。据观察，洪水过程被减缓，并中断的水交换在受损的开口，由于动态运动。与迎浪开孔相比，后开孔的横摇运动幅值大、频率高，对船舶的危害更大。研究还表明，破损船舶的液舱对其横摇响应有重要影响。进一步证明了SPH模型能够处理破损船舶浸水过程中的非线性现象。
The flooding of a damaged ship in waves is a complex process, often coupled with the internal and external liquid motion together with the ship hull motion. Paramount to the operation safety, in order to improve the prediction accuracy of ship motion during the flooding process, the strip theory is applied to study the dynamic response of the damaged ship in beam seas; a smoothed particle hydrodynamics (SPH) model is developed to consider the coupling effects of various factors including internal sloshing of intact cabins and damaged cabins and external waves. The numerical wave tank with a perfectly matched layer absorbing boundary condition is established and validated by the experimental results. The detailed sensitivity study is carried out focusing on the effects of damaged opening sizes, the relative position of opening, and the incident wave and the liquid loading conditions on the dynamic response of the damaged ship in regular beam waves. It is observed that the flooding process was slowed down and interrupted by the water exchanges at the damaged opening due to the dynamic motion. Compared with the opening facing the incident wave, the back one endangered the ship pronouncedly with large amplitude and frequency roll motion. It is also revealed that the liquid tank in the damaged ship imposes a significant influence on its rolling response. It is further demonstrated that the present SPH model is capable of handling the nonlinear phenomenon in a flooding process of a damaged ship.
