| 摘 要： | 在对低压轴流通风机级效率计算公式分析的基础上,考虑到叶轮内损失沿径向分布的不均匀性,应用最优化理论,提出了低压轴流通风机最优流型的数值计算方法,并给出了最优流型与目前风机设计方法中的常用流型对风机性能影响的比较。

| Abstract: | Taking account of the nonuniform radial distribution of the loss insidevane wheel, optimization technique is applied to the numerical computation offlow type for lowpressure axial fans on the basis of analyzing a stage-efficiencyequation given in earlier works. The optimum folw type so determined is com-pared with the commonly--used flow type in current fan design for theirdifferent influences on fan's performance. |
