摘　　要：轴流通风机是广泛使用的通风设备,叶片的结构形式对其切割性能具有重要的影响。采用流体力学仿真分析的形式,对翼型叶片和板型叶片轴流通风机的性能进行模拟分析。结果表明,翼型叶片的全压及全压效率均要高于板型叶片,在进行通风机的设计使用时,可据此进行叶片结构的设计,提高轴流通风机的整体性能。The axial flow fan is a widely used ventilation equipment,and the structural form of the blade has an important influence on its cutting performance.The performance of airfoil-blade and plate-blade axial ventilators is simulated and analyzed in the form of hydrodynamic simulation analysis.The results show that the full pressure and efficiency of the airfoil blade are higher than that of the plate blade,and the blade structure can be designed accordingly to improve the overall performance of the axial flow ventilator when the ventilator is designed for use.
