| 摘 要： | 甲板上浪问题一直是强非线性问题研究领域的热点,它是造成海洋浮式结构物损坏的重要因素.该文完整的阐述了用于研究甲板上浪问题的数值模拟解决方案,并对二维浮动物体的运动响应、甲板上浪进行了考察.模拟在二维数值波浪水池中完成,入射波由冲箱运动生成,水池远端采用海绵层吸收反射波浪,自由液面采用VOF方法捕捉,物体的运动为与波浪的耦合运动.最后将模拟得到的运动响应与试验进行了对比,同时对上浪载荷也进行了分析.

| Abstract: | Green water problem has been a focus for long time in the field of strong non-linear problem.It's an important factor of causing damage to oceanic floating structure.In the present paper, a numerical solution for green water problem is fully described.The emphasis of this investigation is on the dynamic response of the floating object and the green water phenomenon.The simulation is performed in a 2-D numerical wave tank.A plunge-type wave maker is used to generate the wave..To eliminate the reflected waves... |
