Thermal Conductivity of Mixtures of Carbon Dioxide and Ethane in the Critical Region

Abstract

Experimental data are presented for the thermal conductivity of mixtures of carbon dioxide and ethane. The thermal conductivity has been measured with a parallel-plate instrument, as a function of temperature along isochores, so as to obtain detailed information on the behavior of the thermal conductivity of a mixture near the locus of vapor-liquid critical points. The experimental results are in agreement with theoretical predictions from the mode-coupling theory for critical dynamics in binary mixtures.

A Review of Experimental Researches on the Thermophysical Properties of Hydrogen-Containing Mixtures at High Temperatures and High Pressures

“…There are several methods for the thermal conductivity measurement of fluids such as hydrogen, carbon dioxide, water, and their mixtures, mainly including the parallel-plate method, − the coaxial cylinder method, − the hot-wire method, − and the katharometer method. , The previous experimental thermal conductivity data for hydrogen-containing mixtures are briefly summarized in Table S3 in the Supporting Information. It can be seen that the hot-wire method is mostly used at high temperatures.…”
