| 摘 要： | 以连续性方程和N-S方程为控制方程,采用源造波理论和技术,建立了具有造波和消波功能的二维数值波浪水槽,并使用VOF方法追踪自由面来模拟二维情况下的甲板上浪问题.文中就迎浪状态下的固定FPSO和横浪状态下的运动船体断面模型所遭遇的甲板上浪现象分别进行了数值模拟研究.船体的运动规律通过势流理论计算结果给定,在上浪现象模拟计算时,船体的运动采用移动网格技术实现.研究表明,计算结果与试验结果相当吻合,该方法可以用于甲板上浪现象的预报和模拟,可以用于分析预报甲板上浪对浮体的破坏作用.

| Abstract: | A technique of dynamic mesh is specially introduced in a 2-D numerical wave tank to simulate the green water incident on a fixed FPSO model in head waves and oscillating vessels in beam sea conditions, respectively.Numerical results agree well with the corresponding experimental ones.It indicates the present numerical scheme and method can be used to actually simulate the phenomenon of green water on deck, and to predict and analyze the impact forces on floating structures due to green water.It is of great ... |
