Abstract: New expressions for the thermal conductivity of a multicomponent mixture of polyatomic gases have been derived within the semi-classical Wang Chang-Uhlenbeck kinetic theory. Using the Wang Chang-Uhlenbeck formulation of the solution of the kinetic equations, the thermal conductivity is written explicitly, to an arbitrary order of approximation, in terms of a series of effective cross-sections for the first time and in a form suitable for computer implementation. In the alternative formulation of Thijsse, 't Hooft, Combe, Knaap and Beenakker, the thermal conductivity of the mixture is also written explicitly in terms of the effective cross-section. The resulting expression proves to be much simpler than hitherto available.
