I am trying to use r134a vapour as my working fluid for the radial turbine.
For this i had selected r134av from MATERIALS-redkw.ccl, but the enthalpy values in the results generated is not matching with the fluid properties at that particular pressure and temperature.
Please help in selecting the right material.

Well this could have something to do with reference enthalpy (what pressure at temperature is considered Zero enthaly). Also Enthalpy does not have a universal definition, zero enthalpy could be differently from different literature, its the change in enthalpy that must be the same.
