Calculation of transport properties of refrigerant binary mixtures, R۱۲۳/R۳۲ and R۱۲۳/R۲۲ and mixing rule assessment

In this research, we used the Chapman-Enskog solution of the Boltzmann equation to obtain transport properties of the R۱۲۳/R۳۲ and R۱۲۳/R۲۲ refrigerant mixtures. For this purpose, we used the correlation equation of corresponding states of transport collision integrals. In the next step, we evaluated the efficiency of various transport properties mixing rules to calculate transport properties of binary mixtures of refrigerants, R۱۲۳/R۳۲ and R۱۲۳/R۲۲. Finally, by analyzing the deviation diagrams, we presented an optimized model for intermolecular interaction potential parameters and mixing rules to calculate the transport properties of refrigerant mixtures.
