An improved correlation for the thermal conductivity of HCFC-123 (2,2-dichloro-1,1,1-trifluoroethane).
Author(s) : LAESECKE A., PERKINGS R. A., HOWLEY J. B.
Type of article: Article, IJR article
Summary
An updated survey of the existing thermal conductivity data for HCFC-123 is presented. In addition, new wide-ranging thermal conductivity measurements, which have been carried out at NIST, are summarized. These results supplement the existing database and are used for an improved correlation of the thermal conductivity of HCFC-123. The correlation covers the temperature range from 180 to 480 K with pressures up to 67 megapascals or densities up to 1900 kg/m3. The correlation includes an empirical critical enhancement term of a form suitable for industrial use and represents the NIST dataset within more or less 2.22% at the 95% confidence level.
