講演: Hydrodynamics models derived from kinetic theory for weakly ionized plasma flow out of thermal and chemical equilibrium with consistent thermodynamics

要旨: Based on kinetic theory, we give a complete description of the Kolesnikov effect in multicomponent partially ionized plasmas, or crossed contributions to the mass and energy transport fluxes coupling the electrons and heavy particles. The electromagnetic field influence, an ionization mechanism, and  a possible thermal nonequilibrium of the translational energy of the electrons and heavy particles, given their strong disparity of  mass, are accounted for. We conduct a dimensional analysis of the Boltzmann equation and use a multiscale  Chapman-Enskog method with a mixed hyperbolic/parabolic scaling to derive, for the continuum regime,  macroscopic conservation equations and expressions for the transport coefficients and chemical production rates. The model satisfies the law of mass action and the first and second laws of thermodynamics and has a well defined mathematical structure.
