mass flow outlet
 
Hello everybody
I have a question, Please help me.
I am doing simulation a multiphase project (air and 2 solids). I have 3 inlet B.Cs and 2 outlet B.Cs. out lets are as pressure outlet B.Cs. In experiment, solids enter hopper and exit continuously whereas in post processing mass flow out let of solid phases are zero. Why?:confused:

It really depends on how you have setup the problem. Can you provide the boundary conditions you have used? Also how have you checked that solid phase is zero?

Hi
Thanks for your response.
I have used pressure outlet for two out lets as show in attached picture.
In the grain and inert outlet (bottom), we have used a screw conveyor to exit these solid particles only. In other words air do not exit from the bottom outlet.

Excuse my; I have used Report/fluxes to provide mass flow outlet of solid phase. Please help my.
Thank you.
