开发高效、可靠的波浪能转换器（WEC）是波浪能成为商业上可行的能源的先决条件。目前正在对一些WEC进行深入研究，其中包括WaveCat©--一种新的WEC，最近由圣地亚哥-德孔波斯特拉大学申请了专利。在这个意义上，本文介绍了WaveCat的概念及其正在进行的开发和优化。WaveCat是一种浮动式WEC，用于在中等水深（50-100米）下运行。像双体船一样，它由两个船体组成，因此得名。与传统双体船的不同之处在于船体不是平行的，而是会聚的;它们在船尾连接，在平面图中形成楔形。在波浪水槽中进行了1：30模型的物理模型试验，试验中采用了规则波和不规则波。除了波浪和越浪率外，还使用非侵入式系统监测模型位移。物理模型试验的结果将用于验证3D数值模型，该模型将用于优化WaveCat的设计，以在给定的波浪条件下实现最佳性能。
The development of efficient, reliable Wave Energy Converters (WECs) is a prerequisite for wave energy to become a commercially viable energy source. Intensive research is currently under way on a number of WECs, among which WaveCat©—a new WEC recently patented by the University of Santiago de Compostela. In this sense, this paper describes the WaveCat concept and its ongoing development and optimization. WaveCat is a floating WEC intended for operation in intermediate water depths (50–100 m). Like a catamaran, it consists of two hulls—from which it derives its name. The difference with a conventional catamaran is that the hulls are not parallel but convergent; they are joined at the stern, forming a wedge in plan view. Physical model tests of a 1:30 model were conducted in a wave tank using both regular and irregular waves. In addition to the waves and overtopping rates, the model displacements were monitored using a non-intrusive system. The results of the physical model tests will be used to validate the 3D numerical model, which in turn will be used to optimize the design of WaveCat for best performance under a given set of wave conditions.
