摘　　要：运用FLUENT软件对轴流通风机进行了三维实体建模,并对其内部三维粘性流场进行了数值模拟,得到了内部流动的一些规律,并进行了性能分析和预测,为风机的内部结构优化提供了依据和方向。The 3-D solid modeling for axial-flow fan and the numerical simulation for its internal 3-D viscous flow field are carried out by FLUENT software. Some regulars of internal flow are obtained and performance analysis and prediction are carried out. The results have offered important foundation and direction for optimizing internal structure of fan.
