This article describes three methods of correlating experimental data on the heat conductivity of dissociating systems with a single chemical reaction. Criterial equations for the coefficients of thermal conductivity are given.
In studies on dissociating gases, the problem of determining the physical constants of the transport phenomena and, in particular, the coefficient of thermal conductivity is of special interest. In such investigations, however, experimental methods in the high-temperature range are complicated and need further development, while in the case of polyatomic mixtures in which chemical reactions are taking place the practical computations are cumbersome and inaccurate. Therefore, the development of general methods of correlating the available experimental data on the heat conductivity of chemically reacting gases is of definite importance. In this article three methods of evaluating experimental data are discussed in relation to dissociating gases.
