| 摘 要： | 基于粘流软件FINE/marine对半潜式平台进行波浪爬升数值模拟,通过数值计算对比2种模式下立柱迎浪面以及立柱一周的波浪爬升规律,讨论波陡参数和散射参数对立柱波浪爬升的影响以及波浪各频谱成分对波浪爬升的影响。结果表明,平台模式对于立柱波浪爬升产生一定的影响。当波陡参数和散射参数较大时,波浪爬升效应非常显著;波浪经过立柱时,非线性特征愈发明显,波浪高频成分导致的波浪爬升比重不断增加。

| Abstract: | Based on the viscous flow software Fine/marine,the numerical simulation of the wave run-up of the semisubmersible platform is carried out.The numerical simulation is used to compare the wave run-up law of the column facing wave surface and the column in the two modes.The wave steep parameters and scattering parameters are discussed.And effects of the spectral components of the waves on the wave run-up are discussed.The results show that the platform mode has a certain influence on the wave run-up of the column;when the wave steep parameters and scattering parameters are large,the effect of wave run-up is very significant;when the wave passes through the column,the nonlinear characteristics become more obvious,and the wave climbing weight caused by the wave high frequency component is constantly increasing. |
