Dynamics of a gas mixture in an extended kinetic theory

Abstract

The dynamics of a mixture of N rarefied gases is studied by analyzing the set of nonlinear continuity equations for the number densities. Removal and regeneration effects are also taken into account. Various physical situations are considered, corresponding to N=2 and N=3. The relevant diagrams (trajectories in the phase space and curves of the single densities as functions of time) are reported and briefly discussed on physical grounds.
