Experimental study of fan for use of ensilage cutter (III·IV)

Experimental analysis of “Blowing” and “Throwing”, effect of guide vane and correlation between the centrifugal force and the strength of circular disc with fan blade

Abstract

On the third report, we examined experimentaly the mutual relation of the effects of blowing and throwing. On this experiment we also changed the angle of fan blade, air velocity, air volume and r.p.m. and from those results, at the outlet of fan case, the throwing energy were about 4-3.5%. On the fourth report, we considered the various methods of improving the blowing-up performance.
