Ivan, Tutorial 14 gives you a general overview of a simple CFD-DEM 2-Way coupled simulation Chapter 14: Tutorial - Fluidized Bed (ansys.com)

For this application, I suppose you'll need Multiphase flow. So Chapter 14: Tutorial - Fluidized Bed (ansys.com) shows you how to setup such a case.

To model the interaction forces (specifically drag) between non-newtonian fluids and particles, you may also need a special correlation: Chapter 7: Dhole, Chhabra & Eswaran Drag Law Module (ansys.com)
