Shockwave onset with chemical dissociation by the discrete Boltzmann equation
Abstract
This paper deals with the analysis of formation and evolution of 1D shockwaves 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 shockwave formation leads to an initial value problem for a set of nonlinear PDEs which is numerically solved by means of a finite difference method.
