The wave-body interaction of resonant oscillating wave energy converters (WECs) is complex and nonlinear. Rapid development of WECs needs a reliable simulation tool for analysis and design procedure with the ability to capture the instantaneous nonlinear behavior. This paper presents a methodology to study the behavior of a flap-type WEC utilizing hybrid physical and numerical simulation. Dynamic characteristics of the device as isolated and in an array are estimated and the time and oscillation amplitude-dependency of these parameters are explained. This methodology is developed for a device composed of a series of flaps placed on a vertical breakwater. However, the developed algorithm can be updated for any other WEC concept with special consideration on the consequent changes in the load transfer, surrounding hydrodynamic, and wave-structure interaction. This paper increases our understanding and knowledge of all involved phenomena and their direct effects on the natural period and the response and can be used for tunning dynamic characteristics of WEC device to incoming waves. Finally, the developed numerical model is used for the simulation of the WEC to different wave loads and the results are validated with the experimental tests.

谐振振荡波能量转换器 (WEC) 的波体相互作用是复杂且非线性的。WEC 的快速发展需要一种可靠的仿真工具，用于分析和设计程序，并能够捕捉瞬时非线性行为。本文提出了一种利用混合物理和数值模拟来研究襟翼式 WEC 行为的方法。估计隔离和阵列中设备的动态特性，并解释这些参数的时间和振荡幅度依赖性。这种方法是为由放置在垂直防波堤上的一系列襟翼组成的设备开发的。但是，开发的算法可以针对任何其他 WEC 概念进行更新，并特别考虑负载转移、周围流体动力学、和波结构相互作用。本文增加了我们对所有相关现象及其对自然周期和响应的直接影响的理解和知识，可用于调整 WEC 设备对入射波的动态特性。最后，将开发的数值模型用于 WEC 对不同波浪载荷的模拟，并通过实验测试验证结果。
