Thermal Conductivity Measurements of He, Ne, Ar, Kr, N2 and CO[sub 2] with a Transient Hot Wire Method

Abstract

The paper contains a brief account of measurements of thermal conductivity which have been performed by the transient hot wire method at atmospheric pressure and in the temperature range 55–195°C. The measurements were performed on He, Ne, Ar, Kr, N2 and CO2. In the case of the noble gases, the measurements prove to be thermodynamically consistent with the measurements of viscosity performed by R. DiPippo and J. Kestin. This agreement is secured with a margin of error which does not exceed 0.9%. The accuracy of the measurements is estimated to be one of 0.3%.
