water properties in supercritical region
 

hi....plz help me how to input supercritical prop of water into CFX.

Re: water properties in supercritical region
 

CFX 10.0. Make an RGP file or use the Redlich Kwong Equation of State

CFX 11.0. Same as CFX 10.0 or use the IAPWS equation of state.

iapws - if97
 

Hi all!
I have a guestion about iapws-if97 in Ansys Cfx. In my library materials, iapws steam have diferent scope (range) than in The International Association for the Properties of Water and Steam releases.
For egzample: Steam 1 in my CFX have 273.15<T<450 K and 620<p<100 kPa while in IAPWS releases Steam 1 have: 273.15<T<623.15 K and ps(T)<p<100MPa.
If You know why, please answer.

Thanks for attention.
