Modeling 2-phase flow in a 3-D system consisting of 3 distinct sections
 
Hi all,

I need help in Modeling 2-phase flow in a 3-D system consisting of 3 distinct sections.

Problems i am facing,
1. If i use the euler model for multiphase flow, i am unable to have pressure jumps in the system. (do i need to make a compressor and expansion device within the system to have pressure changes?)

2. If i use the mixture model for multiphase flow, i am unable to specify
the fluids within each section.

Details: I have 3 different fluids (A,B,C), 2 gases (A,B) and 1 liquid (C). I need to have component B and C in one section of the system, and component A in the other 2 sections.

Components B (gas) and C (liquid) have the same chemical formula.

I expect to have components B and C change in quantities as evaporation and condensation occurs. (I don't have a UDF to specify the mass transfer and the change in energy due to phase change, i think its required, but i don't know how to make one)

Please help. Any information related to this topic would help.

Thank you,

CFDUSER-A
