define particle diameter and mass conservation
 

Hello,everyone!

I simulate the gas-solids fluidization by Euler-Euler model, and write a udf of define_property(diameter,c,t) to modify the the diameter of particles during the iteration. But I am in confused :confused: that weather the mass of solid phase is conserved? If not, how can I conservate the mass.

Thanks in advanced!

What code are you using?

Have you asked your code's technical support team?

Thanks Otd! I use fluent6.3. Your suggestion is a good idea! But I havn't asked them.
