Reactive \(n\)-species Cahn-Hilliard system: a thermodynamically-consistent model for reversible chemical reactions (Q1713161)

The authors extend the Cahn-Hilliard reactive equations to multicomponent systems, reacting in a reversible way. By defining chemical potentials, the reaction-diffusion processes are described via the generalized Fick law and the mass action law. The approach is illustrated by numerical experiments that support the robustness of the system.
