This paper introduces a novel concept of flap-type wave energy device named the Hull Reservoir Wave Energy Converter (HRWEC). The device is a hybrid of the Pendulum type wave energy converter (PeWEC) and the Pendulor wave energy converter. The device mainly consists of a floating reservoir and a top hinged flap that hangs inside the reservoir. The flap motion is triggered by both the float motion and the fluid motion inside the reservoir and the energy take-off happens through the relative motion between the flap and the float. Because this concept closely resembles the PeWEC, a similar float design is used in the HRWEC to facilitate comparison with available data. The dynamics and power capture are obtained using a frequency domain model, and the power capture is maximized for damping-only control for regular waves. It is shown that this new concept exhibits a broadband response compared to the PeWEC concept, which is linked to an additional mode created by the internal water body motion. As a result, this new concept expected to be suitable candidate for applications in broadband wave climatic conditions.

本文介绍了一种新型的襟翼式波能装置，称为船体水库波能转换器（HRWEC）。该设备是Pendulum型波能转换器（PeWEC）和Pendulor波能转换器的混合体。该设备主要由一个浮动水箱和一个悬挂在水箱内的顶部铰接翻盖组成。浮子运动和储液器内部的流体运动都触发了浮子运动，并且能量的释放是通过浮子和浮子之间的相对运动发生的。由于此概念与PeWEC非常相似，因此HRWEC中使用了类似的浮标设计，以方便与可用数据进行比较。使用频域模型获得动力学和功率捕获，并且将功率捕获最大化，以便仅对规则波进行阻尼控制。结果表明，与PeWEC概念相比，该新概念显示出宽带响应，而PeWEC概念与内部水体运动创建的其他模式相关。结果，该新概念有望成为宽带波气候条件下应用的合适候选者。
