Shock-wave onset with chemical dissociation by the discrete Boltzmann equation
Abstract
This paper deals with the analysis of formation and evolution of 1D shock-waves in the framework of discrete kinetic theory of gases with chemical reactions. In particular, a model of the discrete Boltzmann equation which takes into account chemical reactions of molecule dissociation is proposed. The study of shock-wave formation leads to an initial value problem for a set of nonlinear PDEs which is numerically solved by means of a finite difference method.
