The paper reports accurate measurements of the thermal conductivity of ethane, ethylene, nitrous oxide, air and argon-free air as a function of density at a temperature of 27.5°C. In the case of ethane the experimental data extend over the pressure range 0.6–3.4 MPa, for ethylene over the...

The thermal conductivity of nitrogen and argon between 170 and 300 K at pressures up to 10 MPa has been measured by the transient hot-wire technique. The accuracy of the reported values is estimated to be one of ±0.3%.

The paper reports measurements of the thermal conductivity of eight gaseous mixtures of monatomic gases. The group of systems studied consists of three binary mixtures of neon and argon, four binary mixtures of helium and argon and a ternary mixture of neon, argon and krypton. The measurements...
