how to suimulate the motion of particles
 
1 Attachment(s)
hi all!

i want to simulate the motion of particles in different diameter when the rotor rotates in a closed cavity. like in the attachment figure. how should i do?

thanks!

Your variable diameter means you have different mass for each particle. You should solve for the Newton equation that leads to model such the Maxey equation. You can search for that.

the DPM in the fluent is suitable?

Maybe you can but I don't know for sure, you should read the user guide
