Hello all, I am interested in working on the slurry transportation simulation. In my case, I have to phase system with one carrier liquid, two solid particles, and droplets. Can we simulate CFD DEM simulation using MFix? Kindly help me with this. Thanks in advance.

You can model the fluid + solid (although I would use an appropriate, custom drag model). How are you envisioning modeling the droplets? As a continuum or discrete? Do these droplets coalesce? MFIX does not have a VOF solver.
Thanks for your response. I want to consider droplets as a dispersed phase with a fixed size. For simplicity, we are ignoring the droplets coalesce.
If the droplets are very dilute, then can you treat your droplets as DEM/PIC particles? I don’t know what you are trying to model…
I want to model a slurry system that contains two solid particles (200 and 500 microns) and bitumen droplets with a size of 400 mincron. The total solid fraction is 0.3, and the bitumen fraction is 0.008. The carrier liquid is a non-Newtonian fluid. Currently, I am modeling using the E-E two-fluid model, but I want to try using CFD-DEM simulation. To minimize the complexity of the problem, I ignored droplet breakup and coalescence in the system. I hope it is clear to you.
