摘　　要：根据风力机原理和粘性流体力学理论,应用fluent软件建立二维简化风力机扩散放大器模型,并进行了数值模拟和理论计算;分析比较了几个典型的性能曲线,进一步探讨了模型内的流动特点;该研究对于提高风能利用效率及风能利用技术推广具有一定的指导意义。According to the wind power theory and viscid fluid dynamics the article establish a 2D simple model of diffuser augmented of wind turbine using FLUENT then simulate it by mathematic method and confirm it in theory. We also compare several characteristic curves and find the flowing character. It has a certain extent value of theoretical director and practical popularization to the efficiency of wind energy.
