Thermal conductivity of binary gaseous mixtures containing diatomic components

Abstract

Absolute measurements of the thermal conductivity of binary mixtures of hydrogen + nitrogen, helium + carbon monoxide and argon + carbon monoxide are reported. The measurements were performed in a transient hot-wire instrument at a temperature of 35 °C and in the pressure range 1.8–8 MPa; the reported data have an estimated uncertainty of ± 0.2%.
