Default Phoenics and Heat exchangers

I'm trying do simulate a heat exchanger (Shell-tube, Air-Air) with phoenics. My question is how do I make two domains - one for the hot air outside the pipes and one for the cold air inside the pipes - and allow phoenics to calculate the exit temperature of the fluids?

Thank you in advance

The domain material can be for the shell side fluid. It will be necessary to create a geometry file to represent the geometry of the tube-side fluid. The geometric element can then use a different fluid to the shell-side as it's material attribute. For example, if it was a square pipe, a "blockage" object of different material could be used to represent the tube-side fluid. The two fluids must be seperated by either a plate or solid object.

If the tube density is high, as in a tube bundle, then the heat exchanger can be modelled in PHOENICS by using the classic porous-media approach pioneered by Patankar and Spalding, whereby a separate 1d-analysis is done for the tube side fluid.
