Thermal conductivity of ethyl fluoride (HFC161)
The thermal conductivity of ethyl fluoride (HFC161) was measured in both the saturated liquid and the gaseous phase by the transient hot wire method. Measurements of the thermal conductivity of the saturated liquid HFC161 were reported over the temperature range from 233 K to 373 K and in gaseous phase from 233 K to 373 K along 15 quasi-isotherms and at pressure up to 4470 kPa. The total uncertainty of the gaseous experiment data was less than +/- 3% and that of liquid experimental results would be better than +/- 2%. The results of liquid phase were correlated as a function of temperature and the gaseous phase results were correlated as a function of temperature and pressure for the purpose of interpolation. The absolute mean deviation and maximum deviation of the liquid results from those calculated by polynomial were 0.53% and -1.84%, respectively. The maximum deviation and the absolute mean deviation of the gaseous results from the correlation were 2.94% and 1.18%, respectively. (C) 2014 Elsevier B.V. All rights reserved.
