摘要
基于面向对象的开源软件 OpenFOAM，选择美国国家新能源实验室（NREL）Phase VI 风力机为对象，对以往研究较少的非均匀来流风速作用下风力机三维气动粘性流场进行数值模拟。采用较为接近于真实情况的指数型风剖面，计算了轮毂处风速分别为5、10、15和25 m/ s 四种工况下的叶片表面压力分布、叶片的推力、尾涡等气动力数据，并与均匀来流风速下的风力机气动力学性能进行详细的对比，探讨非均匀风剖面对风力机流场结构和流动特性影响的物理现象和规律。
A numerical simulation of 3D viscous flow field around NREL Phase VI wind turbine was carried out with open source software OpenFOAM under nonuniform wind conditions, about which little research has been done. Exponential wind profile which is close to real situations is chosen. Based on this hypothesis, the following aerodynamic results were analyzed, such as the pressure coefficient distribution at different sections, and rotor thrust and wake structures at mean wind speeds of 5 m/ s, 10 m/ s, 15 m/ s and 25 m/ s respectively. At the same time, the results under nonuniform wind conditions were compared with those under uniform conditions to deepen the understanding of the shear wind effects on the flow structure and flow characteristic around the wind turbine.
