Prediction of the viscosity and thermal conductivity of refrigerant r1233zd (e) including high temperature region.

Prediction of thermodynamic and transport properties are indispensable to design and to manufacture the systems with low Global Warming Potential (GWP) fluids. R1233zd(E) is a potential alternate working fluid for Organic Rankine Cycle (ORC) with low-GWP value. Prediction correlations for viscosity and thermal conductivity of this working fluid are reported in this work based Extended Corresponding States (ECS) model. ECS models coupled with density-independent shape factors (empirical shape factors) or density-dependent shape factors (exact shape factors) are individually applied to predict the viscosity and thermal conductivity. Predicted values with the ECS models are compared with experimental data, and the prediction capability of each model is discussed. In addition, viscosity and thermal conductivity shape factors are introduced to improve the prediction capability.
