On the viscous 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 $${\displaystyle c}$$ is … Ver mais 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 … Ver mais • Allen–Cahn equation • Spinodal decomposition Ver mais • Cahn, John W.; Hilliard, John E.

Web24 de dez. de 2024 · Since the viscous Cahn-Hillid equation arises from the phase-field model by setting c = 0 it may be viewed as a singular limit. Another way to see this is to derive from (2.1), (2.2) a damped wave equation and show how the viscous Cahn-Hilliard equation arises from it. Applying -A to both sides of (2.2), we obtain -UAUI = -yA2 U - Af …
