Abstract As the world moves to a greater reliance on renewable energy, a vital component will be the predictability and dependability of the energy source; tidal energy provides such a solution. Horizontal axis tidal turbines are the most mature technology of all the marine renewable energy devices currently under development, as full-scale porotypes are already being tested and operated. As the industry develops and strives for commercial viability, it is becoming increasingly vital to develop a robust understanding of the complex interaction between the tidal flow, turbine blades and the support structure. This study uses an advanced computational fluid dynamics model to explore the operational fatigue loadings induced on tidal turbine blades. Two factors are considered, the presence of a support structure and varying vertical velocity profile of the tidal current. In order to perform the investigation, a model of a concept 16 m diameter horizontal axis tidal turbine with a monopile support structure is created. An investigation of the operational fatigue loadings due to variations in the positioning and the diameter of the support structure, the tidal turbine blade loads were found to varying by up to 43% of the maximum total thrust force.

使用计算流体动力学对潮汐涡轮叶片进行操作疲劳载荷

摘要 随着世界越来越依赖可再生能源,一个重要的组成部分将是能源的可预测性和可靠性;潮汐能提供了这样的解决方案。水平轴潮汐涡轮机是目前正在开发的所有海洋可再生能源设备中最成熟的技术,因为全尺寸孔型已经在测试和运行。随着行业的发展和为商业可行性而努力,深入了解潮汐流、涡轮叶片和支撑结构之间复杂的相互作用变得越来越重要。本研究使用先进的计算流体动力学模型来探索潮汐涡轮叶片上引起的操作疲劳载荷。考虑两个因素,支持结构的存在和潮汐流的变化的垂直速度剖面。为了进行调查,创建了一个直径为 16 m 的具有单桩支撑结构的水平轴潮汐涡轮机的概念模型。对由于支撑结构的定位和直径的变化而导致的操作疲劳载荷的调查,发现潮汐涡轮叶片载荷的变化高达最大总推力的 43%。
