| 摘 要： | 在分析子午加速风机空气动力有关方程的基础上,通过上机计算,求解出了子午加速风机的最佳毂比。试验证实,按本文所述方法进行设计的等环量流型的叶轮,与按通常方法选择通风机毂比所设计出的叶轮相对比,在各种工况下,叶轮效率都有所提高,文中也给出了在不同设计参数时按本法所应选择的最佳毂比。

| Abstract: | Analysing the aerodynamic properties and relevant equations, the hub ratio of axial fans with meridionally stream acceleration is calculated through the optimum seeking method with the computer program shown. Test results indicate that the efficiency of the impeller designed by this method with iso-circulating air flow is higher in various operating conditions than that conventionally designed. The optimum hub ratios to be selected are given under different design parameters. |
