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 Last edited by CFDUSER-A; December 9, 2009 at 07:18. Reason: more info |
