The Cahn–Hilliard equation is an equation of mathematical physics which describes the process of phase separation, spinodal decomposition, 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 both domains, then the equation is written aswhere is a diffusion coefficient with units of , gives the length of the transition regions between the domains, is the partial time derivative and is the Laplacian in dimensions. Additionally, the quantity is sometimes identified as a chemical potential.
