Abstract

Starting from a Boltzmann kinetic model for a gas mixture with bimolecular chemical reaction, hydrodynamic equations at Euler level are deduced by a consistent hydrodynamic limit in the presence of resonance, namely when the fast process driving evolution is constituted by elastic scattering between particles of the same species. The structure of the resulting multi–temperature and multi–velocity fluid–dynamic description is briefly commented on, and some results in closed analytical form are given for the special case of Maxwellian collision kernel.
