摘要

．本工作的目的是利用Overset框架对规则波下WEC的非线性相互作用进行数值模型OpenFOAM验证和分析。以前的技术，如变形网格方法，在模拟波-结构相互作用时，在处理大的身体运动方面存在问题。因此，采用超置网格技术，分析了系泊浮波能量转换器在自由和系泊衰减试验以及规则波下的相互作用。将数值结果与实验数据进行了比较，并进行了讨论。穆迪库用于计算系泊约束。

Analysis of a floating wave energy converter interaction with waves using the Overset framework

. The aim of this work is to validate and analyze with the numerical model OpenFOAM, the nonlinear interaction of a WEC under regular waves using the Overset framework. Previous techniques, such as deforming grid approaches, present problems to handle large body motions when modelling wave-structure interactions. Therefore, by means of the Overset mesh technique, the interaction of a moored floating wave energy converter in free and moored decay tests and under regular waves are analyzed. Numerical results are compared with experimental data for validation and discussed. MooDy Library is used to compute the mooring restraints.
