Lagrangian Particle Tracking model In CFX

Kushagra

I am facing big times problem with the Lagrangian particle tracking model in CFX. I simulated flow in a hydrocyclone and once I obtained quite good flow field, I started tracking the particles with all the applicable forces applied (Turbulent dispersion force, pressure gradient force, gravity, byouancy) BUT I get wrong results all the time.

Could some one comment his experiences with Lagrangian model and accuracy of it in CFX-11? I have heard from other people as well that they have been facing the same problem as that of mine.

Please help. Thanks very much.
