Abstract
Experimental thermal conductivity data for nitrogen, air, carbon dioxide, oxygen, methane, nitric oxide, and hydrogen have been interpreted in terms of Eucken and Hirschfelder theories. The departure from these theories is attributed to the relaxation of internal energy. At present only a qualitative comparison is possible between the information derived here and that obtained from the studies on the propagation of ultrasonic and shock waves. However, it seems possible to develop a quantitative interpretation for carefully planned thermal conductivity data. Only hydrogen shows an anomalous behavior which is attributed to the uncertainties in the experimental data. This view receives confirmation from the data on binary mixtures of inert gases with hydrogen, and also from an analysis of helium.Keywords
