Résumé

Measurements of viscosity of trans-1-chloro-3,3,3-trifluoropropene (R-1233zd(E)) in liquid and vapor phases are the key attention of the present study and we developed correlations to predict viscosities of saturated liquid and vapor by extrapolating the data to saturation condition, which are useful in industrial design and simulation. R-1233zd(E) is being introduced as a potential candidate to be an alternative working fluid for high temperature heat pumps and organic Rankine cycles (ORCs). In this work, the viscosity of R-1233zd(E) was measured by a tandem capillary tubes method up to 4.07?MPa pressure over a temperature ranges from 314?K (40.85°C) to 434?K (160.85°C) and 394?K (120.85°C) to 474?K (200.85°C) for liquid and vapor phases, respectively. Total standard combined uncertainties in liquid and gas viscosity measurements are lower than ±?3.0% and ±?3.1%, respectively. On the other hand, there were large deviations between experimental data and REFPROP version 9.1 for the liquid viscosity in a range of -25 to -37% and those of vapor phase are -7 to -16%. Experimental data of condensation heat transfer which cannot be correlated well with Nusselt's theory by REFPROP version 9.1 viscosity give a good agreement by using the present viscosity data.
