Hi,
I have a hydrocyclone model supplied by water+sand mixture; a percentage of sand should be separated from water.
Can fluent give me information about this percentage? How much sand (kg/sec) will goes from the top outlet and how much will goes to the down outlet?
It is working with water as follows:
Inlet = 0.84767848 kg/s
Top_Outlet= -0.71924299 kg/s
Down_Outlet= -0.12842806 kg/s


But for Sand:
Inlet = 0.041 kg/s
Top_Outlet= ??? kg/s
Down_Outlet= ??? kg/s

Can't you do a flux report to get the total mass flow and then use a surface integral report to get the mass fraction of your sand?

Many Thanks for your reply, but could you please give me more clarification, what to select from the surface integral tap?

I have a DPM not Mixture or Eulerian.

Again Thank you very much friend.

Your report type could be something like "Area Weighted Average" and then your field variable could be "Mass Fraction of ________". Does that get you what you want?

I'm sure it will work, but my friend, there is nothing in the field variable called "Mass Fraction" .
Many thanks for your kind assistance

Sure there is. The report type is "Area Weighted Average", the field variable is "Species..." and then you choose "Mass fraction of _____". Of course that's if you have enable species transport. If you haven't, maybe I misread your question but it seems you should be keeping track of multiple species. I'm not sure if it's the same when you do a multiphase simulation.

The prolblem is in descrete phase not multiphase. Is there any way to calculate it for descrete phase?

You are right my friend, the problem that i cannot choose between water or sand phase becouse of the DPM not Multiphase Model.
