Hi, I would like to model the condensation of water from the ambient humid air on the circular cooling tube surface (5 deg C) by using ANSYS Fluent. I have tried with Mixture model and Eulerian model for 2D model, however I didn't obtain the condensation behavior as I expected. What specific model should I use to model this problem?


Your reply is highly appreciated! Thank you.

You better use Eulerian Wall Film Model or Condensate Injection (Yes an Injection unsteady particle tracking). Better as beginner to start using EWF.

Best regards, Amine

Any reference that I can refer to? I am not really sure about the settings

Check the tutorials that come with the help system. Not sure if there are any for EWF as it's a newer feature.
