    Cyclone particle study problem

    Alex Brown

      Hello,

      I am new to Solidworks Flow simulation. I am trying to perform a particle study in a cyclone separator. When I show the airflow through the unit, the trajectory reaches the bottom, but when I do a particle study, it stops halfway down. For my particle study I have gravity turned on, ideal reflection. Could someone please explain why the particle study stops half way? I have even tried changing constraints on length and time.

          Have you tried increasing the mesh count around that region? 

          I've had issues many times with particles at high speed impacting a surface and the mesh is so coarse that the particle is now in a solid cell so it stops calculating it.  I doubt that is the case here, but it is possible.

          Otherwise have you tried adjusting the density of your particles to see if it is simply a matter of velocity and taper angle keeping particles suspended in that region?  Flow does not take the particle volume into account (as far as affecting the flow), so you could have a billion particles accumulate in that region and the particle velocity won't change due to particle-to-particle interactions like it would in real life.
