基于自适应弹性结构的超低流速潮流能捕获装置性能研究
Study on Performance of Ultra-Low Velocity Tidal Energy Capture Device Based on Adaptive Elastic Structure
摘要
针对低流速潮流能捕获装置的自适应调控与水动力性能优化问题，提出一种基于自适应弹性结构的超低流速潮流能捕获装置。该装置在叶片设计环节引入掠式设计与后倾设计，借助弹性结构辅助变桨，摒弃了传统的强制同步变桨方式，采用被动独立变桨，具有获能效率高、启动性能强等特点。在时间维度可以适应不同时段的流速变化，在空间维度可以适应不同层深的流速差异，实现了自适应调节。该装置牺牲了双向流的适应性，为单向自适应透平。装置可在0.15m/s超低流速下启动运行，桨距角可随流速变化进行自适应往复调节，有效解决了潮流能发电装置的流速适应性问题。
Abstract
Aiming at the problems of adaptive regulation and hydrodynamic performance optimization of low-velocity tidal energy capture devices, an ultra-low velocity tidal energy capture device based on adaptive elastic structure is proposed in this paper. Swept and backward-tilted designs are adopted in the blade design of the proposed device, and pitch variation is assisted by elastic structures. Different from the traditional forced synchronous pitch adjustment mode, passive independent pitch regulation is applied, which endows the device with superior energy harvesting efficiency and excellent starting performance. It can adapt to the flow velocity variations in different time periods in the temporal dimension and the flow velocity differences at different water depths in the spatial dimension, thereby realizing full-range adaptive adjustment. This device sacrifices the adaptability to bidirectional flow and is designed as a unidirectional adaptive turbine. It can start and operate at an ultra-low flow velocity of 0.15 m/s, and its pitch angle can perform adaptive reciprocating adjustment with the change of flow velocity, which effectively solves the flow velocity adaptability dilemma of tidal energy power generation devices.关键词
