Attenuation of Cross-Flow Fan Noise Using Porous Stabilizers

Attenuation of Cross-Flow Fan Noise Using Porous Stabilizers

This paper presents a qualitative analysis of controlling the cross-flow fan noise by using porous stabilizers. The stabilizer was originally a folded plate. It is changed into a porous structure which has a plenum chamber and vent holes on the front wall. In order to investigate the influences of u...

The results show that the porous stabilizers have not produced considerable effect on the cross-flow fan's performance curve, but the noise radiated from the fan is strongly affected.
