Question about non-constant property water in CFX

Anna Tian · May 7, 2013, 07:15

Hi,

May I ask does CFX have non-constant property water as the flow material? So that I can use it directly without defining like how viscosity varies with temperature.

If yes, where to find it and how to choose that as my flow material?

Yes you can do this.

You need to create a new material and select IAPWS and Water Data as the material group.

You also need to define your temperature and pressure range.

I seriously recommend you read the CFX manual as it explains it very well.
