摘　　要：为开展脉动风场下气动性能数值仿真研究,本文介绍了一种TurbSim/Fluent耦合脉动风场仿真方法。将网格节点信息与求解时间步长导入TurbSim,通过时间迭代得到整个计算域的三维脉动风场。并进行仿真验证,结果发现:当速度入口为湍流脉动风场时,模型时均气动阻力系数与均匀风场相比增大了6.74%,且模型尾流结构也有明显差异。使用脉动风场进行数值仿真对精确流场解析具有重要意义。To investigate the numerical simulation of aerodynamic performance under turbulent wind field,the paper introduces a numerical simulation method of TurbSim/Fluent coupled turbulent wind field.The grid node information and the solution time step are imported into the TurbSim,and the 3D turbulent wind field of the whole computational domain is obtained by time iteration.And the simulation validation was carried out,and it was found that when the velocity inlet was turbulent wind field,the aerodynamic drag coefficient increased by 6.74%compared with that of the uniform wind field,and the wake flow structure was also significantly different.The numerical simulation of turbulent wind field is significance for accurate flow field analysis.
