Thermal conductivity prediction of Trans-1-Chloro-3,3,3-Trifluoropropene (R1233zd (E))

Abstract

R1233zd(E), trans-1-chloro-3,3,3,-trifluoropropene, is a fluorinated propene isomer which may be considered as an alternative working fluids in the field of heat pump and organic Rankine cycle. R1233zd(E) has a much lower GWP than hydrochlorofluorocarbons (HCFC) and their mixtures. In this paper an extension of a previously developed predictive methods for thermal conductivity to a new family of organic compounds, namely R1233zd(E) is considered. A study of the correlation of thermal conductivities of polyatomic gases in the limit of zero density of R1233zd(E) is presented. A theorically correlation scheme based on the formalism Mason-Monchik-Parker theory has been examined and found to be useful for prediction of thermal conductivity data of dilute gas. An attempt is made in this work on the theoretical approach by Predvoditelev, Vargaftik and Filippov proposed for prediction of thermal conductivity for liquid state. The scheme has been tested against the limited amount of experimental data available and shown to be capable of reproducing the thermal conductivities to within few percent. This predicting approach appears promising as an assist in the judgments in the area of this new generation of working fluids data studies.
