WebAug 21, 2024 · The Cahn–Hilliard model (CH), named after John Cahn and John Hilliard who suggested the system in 1958 , describes a prototype of the process of phase separation, by which the two components of a binary fluid or material impulsively separate and form domains, pure in each component. These phase-field systems, are very … WebIn this paper we consider the Cahn-Hilliard mathematical continuum model of spinodal decomposition (or phase separation) of a binary alloy. The phenomenological model is …

The Cahn-Hilliard Model for the Kinetics of Phase Separation
The Cahn–Hilliard equation (after John W. Cahn and John E. Hilliard) is an equation of mathematical physics which describes the process of phase separation, by which the two components of a binary fluid spontaneously separate and form domains pure in each component. If $${\displaystyle c}$$ is … See more Of interest to mathematicians is the existence of a unique solution of the Cahn–Hilliard equation, given by smooth initial data. The proof relies essentially on the existence of a Lyapunov functional. Specifically, if we … See more • Allen–Cahn equation • Spinodal decomposition See more • Cahn, John W.; Hilliard, John E.
