Dear Group,

I am looking at whether it is possible to model the rate of water condensation on a pipe wall downstream of a pipeline Tee. I have a hot and a cold stream coming together and mixing, which results in condensation in the gas phase.

Are there software models available to model this sort of situation? Are there any free tools - I don't have lots of money to look at this.

Any assistance would be greatly appreciated.

Best regards

Andrew Lindsay

Andrew,

It depends on the level of detail that you need.

RELAP5 was developed for analyzing thermal-hydraulic transients in nuclear power systems and will track condensation (steam quality) in piping systems. It's a 1-D code, so you will only be able to see quality vary with distance along the run of piping.

A CFD code (like CFD-ACE+) will allow you to look at condensation using an enthalpy based method that will provide a greater level of detail on spatial variation. It, however, is not free.
