Modeling multiple regimes/regions in boiling of a fluid

adilsyyed · February 1, 2017, 00:30

I want to model boiling of water in a tube. The tube has a shell around it with circulating pressurized hot water.
Water enters with a fixed mass flow rate with subcooled temperature into the tube and gets heated to the point of saturation temperature. Boiling starts and the entire fluid is converted into steam, This steam is heated to superheated temperature before leaving the tube at the other end.

This problem has subcooled, saturation and superheated regions. Can CFX model such a problem?

Yes, CFX can model this. Have a look at the tutorials on the ANSYS customer website for some examples.
