I m using redlich kwong eqn of state for dry steam calculation in a compressor problem with certain temp and pressure as per steam table as a reference state with ref enthalpy and ref entropy values specified zero. But in post processing after a converged solution,the density variations with pressure are not as per std steam table,also the Rothaly is quiet large compared to the pressure and so is the temperature. Does anyone have any idea about how to use Drysteam in cfx11 for compression process.

what steam table do you use?

what p range are you compressing over?

perhaps iapws in cfx11 is the solution
