multi phase
 

hi all
How to define a flow of air+particle?as 1 phase
and water as secondary phase.
Which multi-phase model is appropriate?

Hey
If you have two different velocities for water and air, you can use inlet velocity BC which seprated for water and air (means two inlet velocity Bcs) and set both of them seperately with different velocities

You could define air+particle as a species (multicomponent mixture), so the mixture will be phase 1 and water will be phase 2
