Sand accumulation in a pipe bend
 

Hi all,

Im trying to determine the critical velocity at which point sand will accumulate at the wall in a pipe bend with flowing turbulent water. I am quite new to ansys fluent so any help would be appreciated. I have modelled and meshes my 3d pipe and attempted to apply a multiphase mixture model but im not sure how to view whether the sand has accumulated? Any help would be appreciated on what model to use and how to view the results.

Thanks,
Robbie

You can view the phases contours to check each phase.
