Modeling of Multicomponent Reactive Systems

Abstract

In recent engineering applications reaction-diffusion systems obtain more and more importance for the production and design of functional materials. Therefore, in this contribution spinodal decomposition in multicomponent systems subjected to chemical reactions is studied. To this end, the classical Cahn-Hilliard phase field model is extended by additional contributions from chemical reactions. After deriving the reaction-diffusion model in a thermodynamically consistent way, for the first time a numerical simulation of a ternary chemically reactive phase separating system is presented.
