Collection Efficiencies too high for cyclone separator
 

Hi there,

I am currently modeling a cyclone separator in Fluent, however my separation efficiencies are extremely high for particle diameters < 6 microns, i.e., around 60%. This does not agree with any of the literature I have surveyed. Does anyone have a possible idea as to why this might the case? Any help would be greatly appreciated.

Thank you very much,

Kamran
