You will have water as the continuous phase with air as a eularian bubble phase and powder as a eularian particle phase. ...

But again, the choice of multiphase model depends on the form the air/water fluid takes. I guess the air is fine bubbles and the volume fraction of the bubbles is quite small - is that correct?

The boundary condition is implemented in very different ways between the two methods. So it looks like you first better understand the difference between Eularian and Lagrangian particle models...
