Default how to find property for compressible flow

as of now i assumed that my flow is incompressible and ran the problem.
I'm simulating turbo machine problem.
i would like to simulate compressible(real) model in my problem.

I'm simulating turbine problem. so pressure, temperature and density at inlet to outlet vary. i know the pressure and temperature at in & outlet. using some general relationship i could find the density at in & outlet.

how do i find the varying property(density) of fluid through out the domain?

In cfx solver we are giving property of fluid with respect to standard temperature (ex:25C).
if my problem is about 500c means solver may automatically calculate the property for this temperature?
if it won't means how or where do i get it?

Sounds like you should look at the tutorial titled "Flow in an axial rotor-stator". This will show how this sort of simulation should be set up. While you are reading have a look in the best practices guide for turbomachinery, also in the documentation.

you have to use CEL function to vary the fluid property.think first is it needed for your problem?
