| 摘 要： | 文章讨论了近年来出现的波浪耦合数值模型,并建立了一个前域采用考虑底摩阻的0-1型BEM方法,后域采用VOF方法的双向耦合的波浪数值模型(0-1BEM+VOF模型)。应用模型计算了平缓岸坡上规则波的传播与破碎,并通过与物模试验的结果进行对比,表明了0-1BEM+VOF波浪耦合数值模型可以很好地模拟波浪的传播与强非线性变形,验证了该模型的有效性和准确性。

| Abstract: | The coupled numerical wave models appeared in recent years were discussed in this paper,and a two-way coupled numerical wave model based on the 0-1 type BEM and the VOF method was established.In this model,wave transformation in front of structures was calculated by 0-1 type BEM with consideration of bottom friction,and the interactions between waves and structures were calculated by the VOF method.The effectiveness and accuracy of this model were examined by comparing the numerical results of the regular wave propagation and breaking on gentle slope with the experimental results.The results show that the present model can accurately simulate the wave propagation and strongly nonlinear deformation. |
