Hello friends,

I am trying to simulate a multiphase model consisting of air as continuous phase and dust as discrete phase. This air-dust mixture is carried in a cylindrical duct and needs to be extracted by another duct of larger cross sectional area.

Their is gap between the two ducts and air flows in it so i have constructed a cylindrical setup and named it as atmosphere which is open condition.

I need to know at the end of simulation how much % of air-dust mixture is extracted and how much has been leaked into the atmosphere.

I have velocity inlet and pressure outlet boundary conditions for the ducts but i don't know what to give for the atmosphere as it is a different material (air).

It would be very helpful if somebody could help me up with setting up the boundary condition for atmosphere.

Thanks

Hi,

It would be helpful if you can attach an image of your intended control volume. It is difficult to visualize with the information provided.
