Default Nozzle flow with Multiphase(Eulerian) model

dokeun is on a distinguished road

Now I'm solving 2D axi rocket nozzle with Eulerian Multiphase model because I'd like to simulate the effect of water injection to the plume.
For the chamber "Pressure inlet" with UDF to describe Pressure & Temperature is used.
Material for the plume is like air but Cp of plume is function of Temperature.

The problem is as follow.
As plume propagates through the continuity residual is divergent.
When I used VOF or used not Multiphase model, there was no problem.

How can I fix my problem?

Thanks in advance
