摘要

该研究探索了一种新型的波浪能转换器（WEC）设计，该转换器利用了内部起伏垂直圆柱体和外部固定空心圆柱体之间的相互作用。该设计源于振荡水柱（OWC）型WEC，但将通过Wells涡轮机的气动动力输出（PTO）替换为通过内部升降缸的流体动力动力输出。为了有效地评估最大功率输出，在已经积累了大量海上工业用户的流体动力学软件AQWA（由ANSYS公司开发）中对该系统进行了建模。已经检查了PTO参数的范围，以确保可以实施适当的线性阻尼来模拟PTO力。将气动PTO和流体动力PTO的效率进行比较，表明流体动力PTO比传统的Wells涡轮机更有希望用于OWC系统。

Exploration of power take off in wave energy converters with two-body interaction

The study explores a novel design of wave energy converter (WEC) that utilizes the interaction between an inside heaving vertical cylinder with an outside fixed hollow cylinder. This design originates from the oscillating water column (OWC) type WEC but replaces the pneumatic power take off (PTO) through the Wells turbine with the hydrodynamic PTO through the inside heaving cylinder. To effectively evaluate the maximum power output, the system has been modeled in the hydrodynamic software AQWA (developed by ANSYS Inc) that has accumulated extensive offshore industry users. Ranges of the PTO parameters have been examined to make sure that proper linear damping can be implemented to simulate the PTO force. Comparing the efficiency of the pneumatic PTO with the hydrodynamic PTO, it appears that the hydrodynamic PTO is more promising than the traditional Wells turbine for an OWC system.
