Dear all,
I'm trying to use myltiphase euler foam to simulate a deflector and a gas hood
It's a two phase flow (air water). I have 1 inlet for the gas phase and 2 outlets and 1 inlet and 1 outlet for the liquid phase.
The main issue that I'm facing is that the simulation somewhat looks strange.
The void fractions of air are a little bit non-physical, additionally for some reason the i cannot set the inlet speed and pressure as fixed values cause the courant number goes very high

THe pressure at the inlet is 1.5 , 1.07 at the cone and 1 at the outlet

This schematic explains the geometrical dmain a little bit.
my issue is that physical the void fraction at the botton should always remain 0.2 during all the time steps but because i use fixedfluxpressure as my boundary to my inlet i never reach to that ppoint. Although I showed the results to others (noobs) they said everything is ok. But i strongly believe that the results are misleading.

Boundary conditions used are
Cone pressure fixed
u.air inletoutlet
u.water zero gradient
a.air inletoutlet
a.water internal field

outlet
pressure fixed
u.air inletoutlet
u.water inletoutlet
a.air internalfield
a.water internal field
inlet
pressure fixedfluxPressure
u.air fixed
u.water fixed
a.air fixed
a.water fixed
Which boundary conditions do u suggest that i should use in this case ????
Any help greatly appreciated
