基于BEM与VOF耦合模型的潜堤附近波浪变形研究

Wave deformation around a submerged breakwater by coupling BEM and VOF model

BEM和VOF方法是目前模拟近岸波浪变形的2种有效方法。以这2种模型为基础构建了一个前域应用BEM、后域应用VOF方法的波浪数值计算耦合模型(BEM+VOF模型),并应用该模型对波浪越过水下潜堤的波面变形过程进行研究。结果表明,计算值与实验值吻合良好,说明本文建立的波浪耦合模型可以很好地模拟波浪和结构物的相互作用。

At present, BEM and VOF methods are two kinds of effective methods for simulating the nearshore wave deformation. A new numerical wave coupling model based on both BEM and VOF methods is established by considering the advantages of both methods. In this model, wave propagation in front of structures is calculated by BEM, and the interactions between waves and structures are calculated by VOF method. The applicability and accuracy of this model are examined by comparing numerical results with the experiment results of wave propagation and deformation around a submerged breakwater. The results show that the present model can accurately illustrate the interactions between waves with structures.
