Onsager-Casimir Reciprocal Relations Based on the Boltzmann Equation and Gas-Surface Interaction. Gaseous Mixtures

The approach to the Onsager-Casimir reciprocity relations based on the linearized Boltzmann equation and gas-surface interaction law regarding kinetic coefficients which are neither odd nor even with respect to time reversal is applied to gaseous mixtures. As an example, the slip velocity problem is considered. It is shown that using the reciprocal relations the viscous, thermal and diffuse slip coefficients can be calculated simultaneously solving a unique kinetic coefficient.
