Title: Predicting the properties of mixtures of R22 and R12 part II - Transport properties
Author: Kandlikar, Satish; Bijlani, C.; Sukhatme, S.
Abstract: In general, equations for predicting the transport properties of mixtures are not yet well established. The following procedure is therefore adopted. For a particular property, different equations, which are reasonably accurate for a class of systems and general in their applications, are selected and tested for their suitability for the present system by comparing their predictions with available experimental data of relevance. The only experimental data on mixtures of R22 and R12 is reported by Srichand, Tirunarayanan, and Ramachandran (1) for the viscosity of the vapor. As no experimental data are available for the other properties, the equations selected are checked against the values available for the azeotropic mixtures R500, R502, and R503, whose transport properties are well established (2). The equation which predicts reasonably good values of properties for these azeotropic mixtures is selected for predicting the transport properties of the system R22/R12.
