Method for estimating mixture equation of state parameters.

Eric W. Lemmon, Mark O. McLinden

Open publisher page 22 citations

Abstract

Data for 76 binary pairs were used to develop the method and these data are summarized. The critical temperature, critical pressure, acentric factor, and dipole moment of each pure fluid were used in the final scheme. The values of the range between -106 and +11; a value of zero corresponds to a pseudo ideal mixture. This method is implemented in the NIST REFPROP database for fluids typically used as refrigerants in engineering practice, and should prove useful in the evaluation of new refrigerant blends.
