Thermal Conductivity—Fluids
Abstract
New measurements of the thermal conductivity of HFC-32 made in a coaxial cylinder cell operating in steady state are reported. The measurements were performed along several quasi-isotherms between 300 and 460 K in both liquid and vapor phases. The pressure ranged from 0.1 to 50 MPa. Based on the experimental data, a background equation is provided to calculate the thermal conductivity outside the critical region as a function of temperature and density. A careful analysis of the various sources of errors leads to an estimated uncertainty of ± 1.5%. Comparisons between calculated and experimental values are presented.
