I am doing real gas analysis for that I used RK EOS-UDF (which is available in UDF manual).
I have doubt about the value need to give for H_REF and S_REF. Please someone answer what is value needed to give at this H_REF and S_REF. I have given H and S value corresponds to NIST data but RK EOS over estimates than H and S value. Below is the part of the UDF. /* REFERENCE STATE */ #define P_REF 101325 #define T_REF 288.15 /* OPTIONAL REFERENCE (OFFSET) VALUES FOR ENTHALPY AND ENTROPY */ #define H_REF 0.0 #define S_REF 0.0 |

Does the NIST data use the same reference points (T,P) and (H,S)?
