摘要

本文研究了单鸭子和多鸭子俯仰式波浪能转换器（WECs）的水动力特性、性能效率和功率吸收。计算结果与已发表的实验数据进行了比较和验证。目的是确定里海Astara港口最可能的波浪条件下最合适的WEC大小，同时获得不同几何比（gr）的最佳功率起飞（PTO）阻尼系数。然后在考虑双向和单向PTO系统的情况下，计算不同波高和周期下的功率提取和性能效率。研究发现，当GR为3.2时，鸭子WEC的性能效率更高，并且由于采用双向PTO系统，吸收的功率增加了45.4%。相互作用因子解释了由于WECs的邻近而导致的WECs之间的干扰。研究全面考察了不同规则波特性范围下WEC的动态响应、性能效率、功率提取和相互作用因子。总的来说，这项研究为常规波浪中单个和多个鸭子的行为和效率提供了有价值的见解，并有助于开发和优化波浪能技术。

Performance efficiency and energy harvesting of single and multi-duck WEC under diverse geometrical and operational scenarios

This study examines the hydrodynamic behavior, performance efficiency, and power absorption of single and multi-duck pitching-type wave energy converters (WECs). The comparison and validation of computational results have been conducted with previously published experimental data. The aim is to identify the most suitable WEC size for the most probable wave condition of the Astara port in the Caspian Sea while obtaining the optimum power take-off (PTO) damping coefficient for different geometry ratios (GRs). The power extraction and performance efficiency are then calculated at various wave heights and periods, considering both two-way and one-way PTO systems. It is found that the performance efficiency of the duck WEC with a GR of 3.2 devotes higher efficiency, and also, by engaging the two-way PTO system, absorbs 45.4% more power. The interaction factor accounts for the interference between the WECs due to their proximity. The study thoroughly examines the dynamic response, performance efficiency, power extraction, and interaction factor of the WEC under varying ranges of regular wave characteristics. Overall, this study provides valuable insights into the behavior and efficiency of single and multi-duck WECs in regular waves and can aid in developing and optimizing wave energy technologies.
