（1）CFD-FEM的流固耦合模拟方法
建立了基于CFD-FEM的流固耦合模拟方法，该方法能够应用于多类工程问题的流固耦合仿真分析，例如：柔性平板在流场中的变形、柔性结构物出入水砰击载荷、加筋板的平底结构或楔形体结构的出入水的砰击载荷与水弹性响应、船舶运动与波浪载荷的水弹性仿真模拟。重点研究了船舶在规则波、长峰不规则波、短峰不规则波、畸形波等复杂海况下以迎浪和斜浪航行的运动、剖面载荷、砰击压力、甲板上浪、颤振响应、波激振动、弯扭耦合响应等。
在CFD-FEM双向耦合中，CFD求解器将船体表面上的流体压力和剪切应力传递给FEM求解器；FEM根据外部流体力、刚体惯性力、结构弹性力对结构进行动力分析，并将所得到的结构运动和变形反馈给CFD求解器，用于更新流场信息。结构体表面流体力在从CFD传递至FEM网格上时，借助高斯点和等参映射法沿面元表面积分得到。前期研究采用STAR-CCM+与ABAQUS商业软件耦合。在此基础上，开展了OpenFOAM与CalculiX开源代码的耦合技术。

（2）基于龙骨梁模型的船舶波浪载荷与水弹性模拟
为了解决势流理论方法预报船舶耐波性与波浪载荷的局限性，本团队自2020年起率先开展了船舶波浪载荷与水弹性响应的CFD-FEM双向耦合方法研究。所提出的CFD-FEM双向耦合的船舶水弹性响应模拟方法，其模拟结果几乎涉及或涵盖了船舶水动力与结构响应方面的全部研究内容，包括但不限于：船舶快速性、船舶耐波性、船舶波浪载荷与水弹性、砰击与甲板上浪、船舶结构强度与安全性。
基于所建立的流固耦合模拟技术，实现了船舶在从简单到复杂的各类海况下的运动与载荷响应的全面模拟，包括：迎浪规则波、斜浪规则波、二维长峰不规则波、三维短峰不规则波、三维畸形波、风浪与涌浪混合的双峰谱海浪作用下的船舶响应，并采用水池模型试验和大尺度模型海上试验数据进行数值方法验证。
不同海况下船舶运动与载荷的模拟与试验验证
（3）实尺度船舶流固耦合的CFD-FEM高保真模拟技术
现阶段的数值水池主要针对规则波中刚体船舶的水动力性能进行模拟仿真，已不足以满足现代造船业的应用需求。本团队提出高保真的实尺度数值波浪水池，采用三维海浪和实船结构模拟技术，从而可以模拟真实海况下的船舶运动、波浪载荷和全船应力等综合性能。建立实尺度计算流体动力学模型与全船结构有限元模型，基于CFD-FEM双向流固耦合方法，模拟船体在波浪中的水动力性能与波浪载荷。以集装箱船为例，模拟其斜浪航行于短峰不规则波中，成功再现了船舶在真实复杂海况中的运动、剖面载荷与应力分布。该技术可以获取包括船舶耐波性、波浪载荷、水弹性和结构强度等多方面的综合结果，为深入全面研究船舶在真实海浪中的响应与综合性能提供了新途径。
