摘　　要：采用数值模拟方法对机翼型及板型叶片的轴流风机的气动性能进行了比较。通过对比这两种叶型的风机在相同几何条件下的流量、全压升及效率,得到了不同叶片型线对风机气动性能的影响规律。数值模拟结果表明机翼型叶片的全压效率、通流能力和做功能力等方面比相应的板型叶片具有优越性。By numerical simulation method,the comparisons of aerodynamic performance between airfoil and plate blade axial fans were made.The volume flow-rate,total pressure rise and isentropic efficiency were analyzed under same geometry conditions for the two types of fans to get a clear insight into the influence of the blade profiles on the aerodynamic performance of axial fan.The results show that the airfoil blade fan prevails over the plate one in the aspects of total pressure efficiency,flux capacity and high ...
