Hi All,

For Simulating N2 in the supercritical state which option for density is applicable from the options available in FLUent?I mean which equation of state do describe the density of the fluid accurately? or is it advisable to input the data taken from NIST in the form of polynomial function?

You will need to use a real gas equation of state or use the REFPROP database from NIST in ANSYS FLUENT.

Best regards,

Thank You...I tried the option of REFPROP database from NIST in ANSYS FLUENT & it worked fine.
