Hello Guys
I am modeling a nozzle in which there are
One air inlet
Two Nitrogen inlet
Four Water inlet

According to my experiments
Pressure at Air inlet 6 atm
Pressure at Nitrogen inlet 6 atm
Pressure at water inlet 4 atm
and there respective mas flow rates or velocity

For the above case i want to model a multiphase eulerian eulerian 2 phase flow inside the nozzle.

While running the simulation with
1)Velocity inlet at the boundary condition
2)Using mass flow rate as the boundary condition

I am not getting the pressure profile inside the nozzle.The pressure after convergence of the simulation is in the range of 1.8 to -0.9 atm absolute.

I am hoping a pressure profile from 6atm at the inlet to atmospheric pressure at the outlet what i am not getting via my simulations..


Kindly help me
Thanks in Advance
