I'm using a mixture model. I need a mixture because... water comes immediately with gas.
I'm using incompressible gas.
No I don't use steady state. I use transient analysis.
I use the setting pressure at the inlet and mass flow at the outlet.
I managed to solve the problem using the SIMPLEC method, with great relaxation:
 
Only the pressure makes big leaps:
 
Otherwise everything was set.
I achieved a solution only in the first orders of the SIMPLEC method. What do you think about this?
