Chaotic dynamics of spatially homogeneous gas mixtures

Abstract

The transport of N gases in a background host medium can be described, in the case of constant collision frequencies, by a set of N ordinary differential equations of the Lotka–Volterra type. It is shown that for N=3 such a set exhibits chaotic dynamics generated by a sequence of period-doubling bifurcations starting from a supercritical Hopf bifurcation of the three-species equilibrium state.
