Cyclone efficiency in DPM
 

Hi,

i want to find efficiency of cyclone.
i have following issues.
1. in DPM tab i found three types of Boundary conditions escape, trap,
reflect. for inlet of cyclone i have used trap condition, for dust
outlet i have used trap, for gas outlet i have used escape, for wall i
have used reflect. is is write? (i am not sure for Dust outlet and gas
outlet)

2. how to calculate efficiency?
i have set the injection from inlet in DPM, but i kept it off at the
start of run, after sometime i switch that on.
i have all details of particle size and numbers.

please give me the detail information regarding the same.

if you have some case please share with me.
Thank you for anticipation.
