Hello,
I am trying to perform a conjugate heat transfer analysis of a simple cross flow cooling system consisting of a single pipe carrying hot fluid.This pipe-fluid system is cooled by forced convection by air flowing over the pipe. I have gone through the tutorial on CHT of heating coil , but it contains a single fluid domain and a single solid domain. How can I model a CHT transfer such as the one that I described where 2 fluids seperated by a solid domain is involved? Do I need to perform a multiphase analysis here, because CFX just allows me to define one fluid model for both fluid domains or is there a way I can specify seperate fluid models for the 2 fluid domains in my problem? Any help in modelling this problem is appreciated? Thank You Ajay |

This can be done without requiring multiphase. You have to use the "disallow constant domain physics" option or something like that - search the forum for it, there are a few posts on it.

Dear Ajay
I have exactly the same problem in modelling a heating device. have your problem solved? I searched the forum for "disallow constant domain physics" but nothing exist. Thanks Ali |
