Application to Cyclone or Swirl Tube Simulation

When computing the X50 cut size of a cyclone operating under high vacuum conditions, one should account for its decrease resulting from the influence of the slip correction factor. However, the slip correction factor depends upon the X50 cut size and thus we recommend the following iterative procedure for 

Compute the cyclone cut size from Eq. (5.2.1) which has been modified by the introduction of the slip correction factor  

Compare this new Cc with previous estimate as follows If ABS[Cc — 

X50 computed in Step 4 is the desired cut size under prevailing vacuum conditions. 

A worked example showing how to use this calculation scheme is included in Appendix 12.B.
