| Popis: | International audience; Measurements of the thermal conductivity of ethene performed for the first time, in a coaxial cylinder cell, operating in steady state conditions are reported. The measurements of the thermal conductivity of ethene were carried out along eight quasi-isotherms above the critical temperature. The present data cover the temperature range from 283.46 K to 425.00 K, and the pressure range 0.1–100 MPa. An analysis of the different sources of error leads to an estimated uncertainty (0.95 level of confidence) of ±3%. The parameters of a background equation were determined from experimental data in order to analyze the critical enhancement of the thermal conductivity as a function of temperature and density. Based on the measurement of more than 500 experimental points, a phenomenological equation is provided to describe the thermal conductivity of ethene, from 270 K to 425 K and densities up to 500 kg m−3. |
