摘要:

波浪砰击是发生在波浪与结构物之间的一种强非线性相互作用,其载荷通常具有峰值大、作用时间短的特点.近年来,海上极端环境导致海洋结构物经常遭受严重的波浪砰击,造成生命和财产损失,从而使得波浪砰击问题备受重视.对于复杂的砰击过程,理论分析和模型实验仅能给出砰击载荷的简化解析解及有限的砰击流场信息,数值模拟逐渐成为研究波浪砰击问题的有效手段.目前,国内外学者已经对海洋结构物的波浪砰击载荷特性、砰击作用过程及其影响因素等问题开展了大量的数值研究,并获得了许多重要的研究结论.针对海洋结构物波浪砰击的数值研究进展、现有方法及重要结论进行综述,为波浪砰击数值模拟的进一步研究提供有益参考.

Abstract:

Wave impact is a strongly nonlinear interaction between waves and structures, and its load usually has the characteristics of a large peak value and short duration. In recent years, the extreme environment has frequently led to severe wave impacts on marine structures, resulting in loss of life and property, thus making the issue of wave impact become a great concern. For the complicated impact process, the theoretical analysis and model experiments can only provide simplified analytical solution and limited information on the slamming flow field. Therefore, numerical simulation has gradually become an effective means to study the issue of wave impact. Scholars at home and abroad have conducted a large number of numerical investigations on the load characteristics of wave impact, impact process, and its influencing factors on marine structures, gaining numerous important research conclusions. In this paper, the current progress, existing methods, and important conclusions of the numerical study of wave impact on marine structures are reviewed, which can provide useful references for further research on the numerical simulation of wave impact.

Key words: wave impact, numerical simulation, boundary element method (BEM), smoothed particle hydrodynamics (SPH), numerical tank, volume of fluid (VOF)
