Two phase flow nozzle boundary condition??
 

Hi, everyone

I'm modeling 2 phases flow (gas,liquid) throw Nozzle but have a trouble with boundary condition at inlet.
My model is compressible flow and use homogeneous model in that the density of mixture and mass fraction is calculated by static pressure.
For inlet: I fix total pressure and void fraction D0, another variable is use Von neumann boundary condition.
For outlet: static pressure fixed, other variable.

But when I ran, it shown wrong.
Could you help me to set boundary condition for this?
