摘要
在风洞中正确复现大气边界层特性是保证风洞实验结果准确度的必要条件。本文利用三角形尖劈和粗糙元配合对风洞内热带气旋大气边界层模拟进行了研究,生成了较好反映热带气旋风特性的大气边界层,平均速度和湍流强度廓线与设计值吻合较好,同时提出了用于热带气旋大气边界层内的风力机模型的设计要求。
The accurate reappearance of the atmosphere boundary layer in wind tunnel was necessary in wind tunnel experiments.The atmosphere boundary layer of tropical cyclone was produced by spires and roughness elements in wind tunnel and the profiles of wind speed and turbulence intensity agreed well with the design values.The design requirements of wind turbine model in atmosphere boundary layer of tropical cyclone were proposed according to the simulation.
