摘　　要：运用ANSYS等仿真软件对对旋轴流式风机进行数值模拟与仿真,从风机速度流线、流道内速度与压力矢量以及二级叶片压力等几个方面,对比分析了不同工况下风机内流场的变化情况。通过数值模拟,能真实反映风机内部的复杂流动,为对旋风机的设计和改进提供依据和方向。Software of ANSYS was applied to carry out the numerical simulation of the contra-rotating axial fan. Variation of the flow field inside the fan in various operation modes were compared and analysed in terms of the speed streamines,the velocity and the pressure vector inside the flow passage,as well as the pressure of the second blade. The numerical simulation truly reflects the complex flow inside the fan,which offers references and directions for the design and improvement of the contra-rotating axial fan.
