我们如何研究How we investigate
随着“双碳目标”的提出，风能作为一种可持续能源备受人们的青睐，垂直轴风力发电机因其易安装，全向性和噪声低等特点，适用于城市与海上等复杂环境。阵风是风力涡轮机遇到的一种常见大气条件，风力机的非定常阵风载荷不仅对功率输出有显著影响，而且会降低风力机的结构寿命。利用合适的阵风模型，分析其与风机机翼之间的相互作用，研究小扰动对旋转风机空气动力学影响机理，对提高垂直轴风力发电机气动性能具有重要意义。
As wind energy expands under carbon-neutrality goals, vertical-axis wind turbines are attractive for urban and offshore environments because they are easy to install, omnidirectional and potentially quiet. Gusts are common atmospheric disturbances: their unsteady loads alter power output and may reduce structural life. Appropriate gust models make it possible to study gust–blade interaction and clarify how small disturbances affect rotating-wing aerodynamics.
