On the cahn-hilliard equation
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 is the concentration of the fluid, with indicating domains, then the equation is written as where is a diffusion coefficient with units of and gives the length of the transition regions between t… Web27 de dez. de 2024 · The Cahn-Hilliard equation is a fundamental model that describes the phase separation process in multi-component mixtures.
