Abstract

We report new measurements of thermal conductivity and thermal diffusivity, obtained with a transient hot-wire apparatus, for neon and two mixtures of neon with nitrogen. The measurements were made at temperatures between 58 K and 303 K (ITS 90) with pressures between 0.1 Mpa and 70 Mpa. The data cover only the supercritical gas phase. The number of points reported for pure neon is 829, for the 75 mol % neon -25 mol % nitrogen mixture, 204, and for the 50 mol % neon - 50 mol % nitrogen mixture, 188. Empirical thermal conductivity correlations are provided for neon and the two neon-nitrogen mixtures.
