叶轮轮毂比 impeller hub ratio
它用于整流条件差且轮毂比小的空冷风机上有明显的节能效果。
It has evident effect of energy saving on the use of air cooling fan with poor rectifying condition & small hub ratio.
轮毂比0.325时，周向平均径向速度分布出现明显“畸变”。
The circumferentially averaged velocity distribution of the radial velocity is distorted when the hub/tip ratio is 0.325.
在进行经济技术性分析后，最终确定风机的设计方案，进而确定通风机适当的级型式、叶轮尺寸、轮毂比、转速和叶片数等基本参数。
Final design scheme is confirmed after economic and technical analyse. Then, axial fan 's stage type, impeller diameter, hub ratio , specific speed and the number of blades are decided.
