How to define a RGP file for liquid air?
 
Hello everybody,

I need to simulate the liquid turbine, and the working fluid is liquid air. The pressure range is 0.1Mpa to 5Mpa and temperature reach from 90K to 100k- I'm dealing with a cryogenic application. How can I define this material?

From the doc, we know cfx can define the liquid phase materials, but the doc explains not clearly. I just know when you define the liquid material you need to set the parameter RGP Liquid Properties = Subcooled in the CCL for the liquid material definition. But, in the example of the organization of .rgp file, i don't know how and where to fill the subcooled liquid tables. Besides, is it necessary to fill the "superheat" tables in the definition of a liquid material?

Thanks a lot!
