【摘要】 优良的波浪环境条件是研究非线性波浪和浮式结构物相互作用问题的基础。文章在数值波浪水池中对不规则波浪进行了数值模拟,造波通过摇板的运动实现,消波通过在水池后段设置消波区实现,自由液面由VOF方法捕捉。对计算所得的波浪时历进行谱分析并将所得谱与理论谱进行了比较,吻合良好。更多还原

【Abstract】 Quality of wave environment is the basis for studying the nonlinear interactions between water waves and floating structures.In this paper,a numerical wave tank was used to simulate the irregular wave.Flap type wave-maker was adopted for generating waves and wave reflection was handled properly through setting up wave absorption zone.VOF method was employed for tracking the free surface.Spectrum analysis was performed on time trace of waves and the calculated spectrum agreed well with the theoretical spectrum.更多还原
