Study of viscosity and thermal conductivity effects on condensation characteristics of some new alternative refrigerant mixtures

Abstract:

In this paper, a numerical study of the impact of the transport properties on the condensation characteristics of certain refrigerant mixtures is presented. New correlations have been developed to calculate the thermal conductivity and viscosity of some alternative refrigerant mixtures such as R-507, R-404A, R-407C, and R-410A. In addition, new improved condensation correlations have been developed and presented for pbkp_redicting the heat transfer coefficient and pressure drop. The results clearly showed that the condensation characteristics were well pbkp_redicted using the newly proposed correlations with mean deviation of ± 10 and 20% for the heat transfer coefficient and pressure drop respectively.
