摘　　要：借助FLUENT流动分析软件,根据计算流体力学理论,对一单级后置导叶轴流通风机的内部流场进行了全三维数值模拟,同时求解了叶轮、导叶(动区/静区)流场,获得了风机内部流场中重要的流动细节及规律,并在此基础上对该风机进行了流线型优化设计,使全压效率从74.12%提高到了77.11%。A complete 3-D numerical simulation for an axial-flow fan with back vane is studied based on the theory of CFD, including the impeller and vane （moving and stationary area）, with the help of a fluid analysis software FLUENT. Many detailed and important information and regulations are obtained. Based on this calculation, the optimization design for fan is finished. The total pressure efficiency has risen from 74.12% to 77.11%.
