I want to design a mixing chamber where air enters this chamber and interact with already stationary placed flour and exit the chamber, the main purpose of this chamber design is to ensure enough mixing so it ejects steady flow of air+ flour. 

i have couple of designs already but my question is how can I place stationary flour particles so air comes with a velocity and mixes with the particles and create a mixed flow?

You can start by letting "floor" particles rain without any air and when the particles get settled you just start with the air inflow.

Which Geldart group are your floor particles belonging to?

Thank you for your response, I am testing with "Flour" powder particles the one used in baking, it is classified as group C, for now I made a simple cube with inlet and outlet air path, do you suggest to specify the DPM as a group with xyz coordinates in the middle of the cube to let it rain and settle as you said, or can I specify the down side of the cube as a surface injection with a very small injection velocity ?
