摘要
采用NRELS809翼型数据建立了水平轴风力机的整体模型及整机的流场模型.利用Fluent软件对模型进行仿真计算.结果表明,叶片截面形状对流场变化有影响.其中气流在叶片前后流场变化较大,叶片后部易出现涡流,存在负压,而叶片长度方向上的截面气流也有变化.
NRELS809 airfoil is chosen, the whole model of horizontal axis wind turbine is built. By simulating the model by Fluent software, it is found that the section shape of blade has a great influence on flow field, and the air flow in the front and the back of blade changes greatly, the vortex and negative pressure appear in the back of blade, and airflow changes in the section along the blade.
