Abstract In this work, we present several applications of the 2D-3D multi-domain couplings for Navier-Stokes models developed and validated in its companion (Di Paolo et al. (0000), submitted). The methodology is used to carry out some relevant simulations which include long regular and irregular waves, solitary wave propagation on a shallow foreshore, focused wave group transformation on a planar beach, wave impact on a cylinder and finally, the numerical twin of a complex laboratory experiment to analyse the performance of a perforated breakwater under wave action. Results agree well with the full 3D simulations and laboratory experiments and demonstrate the feasibility of using the 2D-3D coupled methodologies presented in Part I to successfully replace full 3D modelling. For all the cases considered, the application of coupled methodologies have resulted in a drastic reducing of the computational time without decreasing the accuracy of the full solution.

在 OpenFOAM® 中使用 Navier-Stokes 求解器的多域耦合进行波和结构交互。第二部分：复杂案例的验证和应用

摘要 在这项工作中，我们展示了 Navier-Stokes 模型的 2D-3D 多域耦合的几个应用程序（Di Paolo 等人 (0000)，已提交）。该方法用于进行一些相关模拟，包括长规则和不规则波，浅滩上的孤立波传播，平面海滩上的聚焦波群变换，波浪对圆柱体的影响，最后是复杂实验室的数值孪生。分析穿孔防波堤在波浪作用下的性能的实验。结果与完整的 3D 模拟和实验室实验非常吻合，并证明了使用第一部分中介绍的 2D-3D 耦合方法成功取代完整 3D 建模的可行性。对于所有考虑的情况，
