The paper reports new measurements of the thermal conductivity of mixtures of neon and argon with methane at a temperature of 27.5°C. The measurements have been performed with a transient hot-wire instrument within the pressure range 1 to 22 MPa and the results have an estimated uncertainty of ±0.3%. The thermal conductivity data for the mixtures in the limit of zero density can be represented with the aid of the best available kinetic theory formulae, but not within their experimental uncertainty. The density dependence of the thermal conductivity of the mixtures is adequately described by a semi-empirical correlation scheme based on the modified Enskog theory.
